The following is a list of cognitive science-ish events information etc. that
have been sent out in last few weeks. It seems that there's enough to warrant
collecting together and forwarding what makes itself available, but this is by
no means an attempt at comprehensiveness -- I copied/typed in whatever I got in
my mailbox (no glorious newsletter to inspire wholesale revolution this year).

"Formalist Heresy: Mathematics is based on Programming"
Abstract: We argue the merits of a formalist approach to mathematics, with a
semantics based on programming. We examine the challenges to the formalist
position posed by Cantor's diagonal argument, by G"oedel's incompleteness
theorem, and by Turing's halting problem.

"LP, a logic for Representation and Reasoning with Qualitative Statistical
Knowledge"
Sandford Fleming building, rm 1105
Abstract: Driven by a need to represent the vaguely quantified statistical
knowledge used in common sense reasoning, and the inadequacies of previous
probability logics, a new logic, called Lp, is developed. Lp is capable of
representing statistical knowledge in an efficient manner, through the
formation of probability terms from open formulas. By making the denotation
of these probability terms a separate sort, many forms of vaguely quantified
statistical information can be efficiently represented, and reasoned with
through a sound and complete proof theory. If more exactly quantified
information is available, this too can be represented and reasoned with.

AI Seminar

"On the Semantics of Default Logic"
Abstract: At least two different types of structures are proposed as correct
semantics for logic of defaults: Minimal sets of formulas closed under defaults
and fixed points of Reiter's operator GAMMA. In some cases these notions
coincide, but generally it is not the case. In addition Konolige identified
Reiter's fixed points (so called extensions) with certain class of
autoepistemic expansions of Moore.
We identify another class of structures for defaults, called weak
expansions and show one to one correspondence between Moore's autoepistemic
expansions and weak extensions. This functor extends Konolige's correspondence.
We show that expressibility power of autoepistemic logic (with expansions as
intended structures) is precisely same as default logic with weak expansions.

Other Notes
-------------------------------------------------------------------------------
Last year the McLuhan program sponsored a newsletter to track cognitive science
events around UofT; it died due to both monetary and energy starvation.
The McLuhan Program is short on funding, and has narrowed it's interests as a
result of their 5 year review last Spring, so there's no established central
resource for cognitive science. On the other hand, the University is setting
up (or has already set up) a Center for Cognitive Science to take up such a
role, and Jennifer Cohen of CACS (see below) has started putting together a
very relevant monthly publicaton. Much of the events information above comes
from that newsletter.
If I continue to get information from sources around campus I'll post whatever
comes in, though I may not have time to keep at it. [Even this little posting
will take over an hour, which may be more time than is available.]
-------------------------------------------------------------------------------
Jennifer Cohen now publishes "The CACS Newsletter" on a monthly basis.
(CACS = Center for Applied Cognitive Science, OISE) She is interested
in information relating to any and all Toronto area cognitive science.
Subscription is free.

The McLuhan Program in Culture and Technology now charges a $5 annual fee
for their newsletter (times are tough for them). Contact Sylvia Wookey
at 978-7026 to find out about relevant aspects of the program. They have
discontinued their cognitive sciences activities, but much of their focus
is still interesting.
-------------------------------------------------------------------------------
Another edition of the physiology newsletter, "Advances in Physiology", Fall
1988, has been recently published. Available through the graduate office in
Physiology.
-------------------------------------------------------------------------------
The "Neuroscience Newsletter", published by the Neuroscience Program,
continues publication in 1988-89. Contact the program secretary, Winston
Dixon, at 978-4894, to get on the mailing list (free).
