I'm an Assistant Professor at the University of Virginia. My interests are geometric representation theory, knot homology and categorification.

comment Beilinson-Bernstein localization: $\mathfrak{g}$ action on $G$-equivariant sheaf
@NilayKumar The function $g$ is the derivative of f with respect to $a$. This is proven exactly like the multiplication rule in first year calculus.

comment Deformations of associative algebras and Hochschild cohomology
You're really trying to reinvent the wheel here. This is all in Hochschild's papers "The deformation theory of rings and algebras I-IV" from the 60's.

comment Mixed Hodge structure and cup product
Also, seriously? 3 close votes? I understand it's not the best written question and the answer is reasonably "well-known," but mixed Hodge structures are too basic for this site now?

comment Realistic exit strategy for pure mathematics faculty at liberal arts colleges
While I think this is a good question, it seems unlikely that there really is a good answer (as they say, it's tough to make predictions, especially about the future). In particular, the amount of preparation needed depends quite a bit on how many colleges are closing/downsizing in the hypothetical scenario where yours does. A couple per year, or dozens?

comment Continuous families of finite subgroups of a Lie group
@PaulTaylor Which Misha answered. The space of representations of a finite group into a Lie group is a discrete union of conjugacy classes, so any continuous map from a connected topological space lands inside one conjugacy class.

comment counting how many boxes from a given Young tableau contribute to hook length made out of two YTs
Sorry, what's your question? I don't think "Please write the proof of this combinatorial lemma for me" is an appropriate use of the site. How the heck did you come up with this if you don't already know the proof?
