The Special Session in Ergodic Theory & Dynamical Systems
came off quite successfully.

Two questions that were mentioned, but not so loudly, and so might be
- Which groups admit mixing actions that are not mixing of all orders?
[I (prob'ly JK) asked]
- Which groups admit zero entropy mixing actions? (Dan asked)
Let z be a complex number and k(n)
(for n=0,1,2,...) a sequence of
integers such that
k(n+1)-k(n) is either 0 or 1 for all n.
Denote by C(n,k) the binomial coefficient n choose k. If z to the power
C(n,k(n)) tends to 1 as n tends to infinity, then z=1.
This conjecture is much stronger than weak mixing of the Pascal adic
transformation with respect to any Bernoulli measure on the 2-shift.

will be held here, University of Florida, on
12-13 March1999 (Friday & Saturday). The first talk
of the Special Session starts at 8AM on Friday, and the last talk
ends at 6PM on Saturday.

YOUR TRAVEL PLANS: Some of you may wish to stay in Gainesville through
Sunday, or Monday (March 14,15). On March 15, the first Erdos
Colloquium will be held here. The speaker is Ron
Graham of A T & T Labs Research.
On Sunday, 13March, I'm hoping that a number of us can have a
post-conference gathering and BBQ at Ginny or Poe Springs
(there are three springs within a 25 minute drive). In addition to providing a
pleasant environment for mathematics, these Springs have year-round 72degree
swimming, volleyball facilities, hiking trails, rental canoes. At Ginny
Springs one can go tubing.
The tentative plan is to leave for the Springs around 10AM on Sunday, and
drive back around 4PM. Naturally, some cars might leave earlier to get some
folks to the airport.

Of the several
listed, I am familiar with two:
The Holiday Inn—University Center hotel is the closest to the math dept.;
perhaps a 3 minute walk. It
has a Denny's restaurant downstairs, which I am not particularly fond of, but
there are several other restaurants within a 5 minute walk.
I like the nearby Chaucer's restaurant, which has a
limited, but good, menu, and which is open for breakfast/lunch/dinner. There
is also a
bagel place right across the street from the hotel, as well as
Leonardo's pizza, both of which are pretty good. The latter is something of a
student hangout; it serves various fancy forms of coffee. There is also a
good, interesting, Berkeleyesque (but tiny) restaurant called Rhapsody across
the street from the Holiday Inn.
The Radisson Hotel is a long walk from the department;
there is a free shuttle for conference
participants. I've not dined at its
restaurant, but I've been at a catered event at the hotel, and the food was
