Number of disjoint partitions

Abstract:

Let *X* be a finite collection of sets. Given *n*>*1* what is the maximal number
of ways disjoint union of *n* sets (elements from *X*) is again a set in *X*? I
will show you how to find good bounds of this quantity in terms of *n* and
the cardinality of *X*.

Before the talk, at 3:10pm, there will be tea and cookies in Wean 6220.
