Scientific Computations
on some Mathematical Conjectures
This talk will show how some recent computational work has shed new
light on the following unsolved mathematical conjectures:
1) Bernstein's conjecture in approximation theory;
2) Polya conjecture (related to the Riemann Zeta
hypothesis);
3) conjectures with respect to global descent
methods for determining zeros of polynomials;
4) one-ninth conjecture in rational approximation.

Participant Systems
A Participant System is a distributed computer system that
facilitates the simultaneous interaction of several persons working
together, possibly over several physical locations, on a shared complex
task. To do so, it must support communications, multiple views, and common
data, action and cognitive space. Such a system must coordinate access to a
common problem representation, and contain sufficient knowledge and exper-
tise in the problem domain to integrate the activities of the users, and
even to participate as one of the experts. This represents a new paradigm
for computing, a departure from the traditional one-person-to-one virtual
machine mode, to one that more directly reflects the nature of human prob-
lem solving in the group situation.
Participant Systems differ from computer conferencing systems in
several ways. They are real time, rather than asyunchronous. They deal with
the solution of specific tasks, rather than the communication of text-based
messages; they are therefore knowledge based, in contrast to computer
conference systems, which are communications oriented but have no specific
semantic knowledge of what is being discussed.
