"Divisible abelian groups realizable as the
multiplicative group of a field"
ABSTRACT: L. Fuchs posed the question of which abelian groups
can be realized as the multiplicative group of nonzero elements
of a field. Many partial results have been obtained (though it
looks like a "nice" classification of such groups is untenable).
In particular, the structure of the multiplicative group of algebraically
closed and real closed fields was determined some time ago. More
recently, Mott, Contessa, and Nichols proved that an infinite direct
sum of copies of the rationals is isomorphic to the multiplicative
group of some field. In this talk, we consider the more general class
of divisible abelian groups and completely determine which groups
in this class can be so realized. A few corollaries and applications
will be included. To mention but one: if F is a field of characteristic
0 whose multiplicative group F* is divisible, then F* is isomorphic to
K*, where K is an algebraic closure of F, though F itself need not be
algebraically closed. We contrast this with the characteristic p case.

ABSTRACT: We talk about the probabilities behind this fascinating
and energized game of chance. I will bring dice (or bring your own
favorite 6-sided dice) so that we can play a little bit.
