The Department of Mathematics and Statistics invites students, faculty, and staff to attend the upcoming colloquium with speaker Dr. Basil Nanayakkara on Tuesday, March 17, from 2:30 PM to 3:30 PM in MCJ404.  The talk is entitled The Zariski topology on the spectrum of a nil-clean ring.

Abstract:

We will show that the clopen subsets of the prime spectrum of a commutative nil-clean ring form a Boolean lattice. This is an interesting mix of topology and abstract algebra.
