APPROPRIATE PROOF TECHNIQUES
A. H. Zemanian

The usual techniques for proving things are often inadequate because they
are merely concerned with truth.  For more practical objectives, there
are other powerful --- but generally unacknowledged --- methods.
Here is an (undoubtedly incomplete) list of them:

Proof by Blatant Assertion:  Use words and phrases like
``clearly ...,'' ``obviously ...,'' ``it is easily shown that ...,'' and
``as any fool can plainly see ....''

Proof by Seduction:  ``If you will just agree to believe this,
you might get a better final grade.''

Proof by Intimidation:  ``You better believe this if you want to pass
this course.''

Proof by Interruption:  Keep interrupting until your opponent gives up.

Proof by Misconception:  An example of this is the Freshman's Conception
of the Limit Process:  ``2 equals 3 for large values of 2.''  Once
introduced, any conclusion is reachable.

Proof by Obfuscation:  A long list of lemmas is helpful in this
case --- the more, the better.

Proof by Confusion:  This is a more refined form of proof by
obfuscation.  The long list of lemmas should be arranged into circular
patterns
of reasoning --- and perhaps more baroque structures such as
figure-eights and fleurs-de-lis.

Proof by Exhaustion:  This is a modification of an inductive proof.
Instead of going to the general case after proving the first one, prove the
second case, then the third, then the fourth, and so on --- until a
sufficiently large n is achieved whereby the nth case
is being propounded to a soundly sleeping audience.

REFERENCES

I don't have any.

Of course these proof techniques are in common usage.  The purpose of this
paper is to identify and categorize them.  However, I cannot claim
priority for all categories, nor can I tell when, where, or from whom I first
encountered such ideas.

What's needed is an archival service.

The Department of Aviation Computer Science invites applications
for a tenure-track position at the assistant and associate professor
level. The position will begin in Fall 1994.  Candidates must have a
Ph.D. in an engineering or computing discipline (or a closely related
area), a commitment to quality teaching, and they must possess the
capability of directing graduate students in applied research.
The Department's curriculum and research efforts are centered around the
development of computer systems related to aviation/aerospace problems.


Applications are solicited from candidates who have undergraduate/graduate
teaching experience in real-time systems, who have experience in directing
graduate research, and who have acquired funded research in an area
of real-time systems.

Preference will be given to candidates with a background in software
engineering and proficiency in Ada implementation. The Master in
Software Engineering program has two areas of concentration:
capability maturity model with personal process concentration and
real-time and simulation software development. In Fall 1995 we shall
move to a new building with expanded laboratory space and provision
for a separate real-time laboratory. The candidate is expected to help
The Department with real-time hardware and software acquisition
and the laboratory design.

The Department also may have an opening for one year visiting position
for a candidate matching the above requirements.

The Daytona Beach Campus of Embry-Riddle has 5000 students and
the Aviation Computer Science Department has eleven faculty,
over 200 computer science majors and minors, and 30 graduate students
in Master of Software Engineering program. The classroom
instruction is supported by the Academic Computing Laboratory. In
addition to a standard microcomputer lab with a network of 100

          This book is a self contained compendium of easily implementable
          adaptive control algorithms that have been developed and
          applied by the authors for over 10 years.  These algorithms do not
          require explicit process parameter identification and have been
          successfully applied to a wide variety of engineering problems
          including flexible structure control, blood pressure control, and
          robotics.  In general, these algorithms are suitable for a wide
          class of multiple input-multiple output control systems containing
          significant uncertainty as well as disturbances.

          The text has been written so that persons with a basic linear
          multivariable systems background will be able to
          develop and apply the adaptive algorithms to their particular
          problems.  Thus, besides developing the theoretical details of the
          algorithm, the text gives considerable emphasis to design recipes
          and to representative applications in flight control, flexible
          structure control, robotics, and drug infusion control.

          The text has been prepared in a manner such that it will be
          possible for readers to actually use the algorithms even though they 
          do not thoroughly understand the complete theory.  This is the result
          of a separate emphasis on the algorithm structure, its implementation,
          and the recommended procedures for tuning.  This should appeal to a
          practicing design engineer.

          It is also suitable either as a reference or as a text for a
          graduate course in adaptive control systems.

          The key features of the text are
              Algorithm theory and development
              Algorithm implementation
              Algorithm applications

                  FROM IDENTIFICATION TO LEARNING



                 a NATO Advanced Study Institute

   cosponsored by C.N.R - Consiglio Nazionale delle Ricerche of Italy



                     Villa Olmo, Como (Italy)

                 August 24  -  September 2, 1994


The purpose of this NATO Advanced Study Institute is to present an updated
picture of the present state in the mathematical theory of evolutive model
building. The conceptual links leading to learning algorithms starting from
model identification and foundations of adaptive control will be explored.
The speakers will present tutorials on the classical statistical approach,
the deterministic behaviour-based approach and the H-infinity approach to
identification. Basic concepts of adaptation and self-tuning will be
reviewed. The structure of recursive algorthms and various related
computational aspects will be discussed. The concepts of learning from
examples will be introduced, and the possibilities offered by neural
networks will be critically evaluated.

Now in its 13th year, IEEE INFOCOM is the premier international technical
conference devoted to computer communications and networking.  Papers
presented at INFOCOM represent the leading edge of understanding and
development in this fast-moving field, and are accepted only after a
rigorous review process.  The half-day and full-day tutorials are given by
leading experts and afford the participant an opportunity to stay current
with the latest advances in computer communications and networking. In
addition, in 1994 INFOCOM is offering for the first time a full-day
Gigabit Networking Workshop, consisting of informal short presentations
on "hot topics" and full paper presentations on applications enabling the
large-scale deployment of gigabit networks. IEEE INFOCOM'94 is sponsored
by the IEEE Computer and Communication Societies. The Gigabit Networking
Workshop is sponsored by the IEEE COMSOC Technical Committee on Gigabit per
Second Networks.

MARK YOUR CALENDAR!

1994 SIAM FORUM MATHEMATICS IN INDUSTRY: THE JOB MARKET OF THE
FUTURE July 23, 1994 Holiday Inn at the Embarcadero, San Diego,
California

Panel sessions and presentations for mathematicians in business,
industry, government, and academia will focus on The Job Market
of the Future:

Mathematics in Smaller Firms A panel discussion of practices,
opportunities, and experiences of mathematicians working in
smaller firms, a rapidly growing segment of American business.

Experiences of Recent Industrial Hires Brief presentations and
discussions from some who recently started working in industry.
How did they find their positions?  What do they do?  What do
they wish they knew in graduate school that they know now?

Hiring: the Manager's Perspective Managers discuss the processes
and practices of hiring industry and government. Who makes the
decisions and how?  What are current needs, practices and
opportunities?  Who is getting what kinds of positions?

Bridging from Academia to Industry How do academic
mathematicians build bridges to industry?  What programs are
available for student and faculty internships in industry and
government?  What support can university relations offices
provide?  How are alumni networks built?

Non-Mathematicians Who Do Mathematics In Industry Many
individuals whose terminal degrees are not in mathematics work
in industry as applied mathematicians.  How did they come to
applied mathematics?  What kinds of problems do they work on?
How did they get their positions?  What can those with
mathematics degrees learn from their experiences?

The Forum is sponsored by SIAM to promote exchange within the
community on important issues and to inform and energize it.
Extensive audience participation is always a key feature of the
SIAM Forum.  Informal meals and receptions will offer further
opportunities for interaction and networking.

This forum is being conducted with partial support from the
Department of Energy.
