On the Growth of the Counting Function of Stanley Sequences
Abstract: Given a finite set of nonnegative integers A with no three-term arithmetic progressions, the Stanley sequence generated by A, denoted S(A), is the infinite set created by beginning with A and then greedily including strictly larger integers which do not induce a three-term arithmetic progression in S(A). Erdos et al. asked whether the counting function, S(A,x), of a Stanley sequence S(A) satisfies S(A,x)> x^{1/2-epsilon} for every \epsilon > 0 and x > x_0(\epsilon, A). In this talk, we answer this question in the affirmative; in fact, we prove a slightly stronger result.

Syzygies
Abstract: I will give a very brief overview of syzygies, part of algebraic geometry, which has close relationship to combinatorics(e.g polytopes), representation theory(e.g Young tableaux). I will talk about Green's N_p property and a result of Prof Schenck, Eisenbud-Goto conjecture about regularity.

Life After Comps Panel Discussion
Abstract: All Math Grad Students are invited to attend "Life After Comps Panel Discussion" on Thursday, April 14, from 4:00-5:00 p.m. in 245 Altgeld. Several of our current PhD students will discuss topics such as the process of finding a thesis adviser, moving into thesis research, etc. There will be lots of time for questions and discussion, so please come and benefit from others' experience. And for those of you who are already beyond this stage in your studies, please come and share your own experience, whether you are officially on the panel or not!
