"Semisimplicity and the Hopkins--Levitski Theorem"

This semester we'll be meeting weekly to learn more about ring theory, mostly going through Lam's two books --- there are many interesting results in those books which will be "good to know". Starting off, we'll aim to learn the Hopkins--Levitski Theorem, one of whose (many) consequences is that the descending chain condition implies the ascending chain condition. Everyone is welcome. See you there!

"More on definable functors, and imaginaries"

Thomas Parker, Michigan State University

“Paths of holomorphic curves and the GV conjecture”

Wentang Kuo, Pure Mathematics, University of Waterloo

"On a problem of Sidon"

Christopher Hawthorne, Pure Mathematics, University of Waterloo

We begin chapter 4 of Goldblatt. (Category theory background from chapter 3 will be assumed.) We introduce subobjects and subobject classifiers; time permitting, we will get to the definition of a topos.

"A Proper Separation -- The Variety Show"

Well, it has only taken two years, but we are finally ready to give the scheme-theoretic definition of "variety".  Along the way, we discuss the notions algebraic geometers use in place of "Hausdorff" and "compact Hausdorff", namely "separated" and "proper" morphisms.  Somehow, it seems fitting to talk about "separation" as we bring this seminar to a close...
