Computer Science/Discrete Mathematics Seminar II

Bounds on roots of polynomials (and applications)
10:30am

I will discuss methods for deriving bounds on the roots of polynomials, and how one can use such bounds to assert the existence of combinatorial structures with certain spectral properties. This will include introducing the "method of interlacing...

Computer Science/Discrete Mathematics Seminar I

Efficient empirical revenue maximization in single-parameter auction environments
Yannai Gonczarowski
11:15am

We present a polynomial-time algorithm that, given samples from the unknown valuation distribution of each bidder, learns an auction that approximately maximizes the auctioneer's revenue in a variety of single-parameter auction environments...

Homological Mirror Symmetry (Mini-Course)

Mirror symmetry for moduli of flat bundles and non-abelian Hodge theory
10:45am

I will discuss a construction of the homological mirror correspondence on algebraic integrable systems arising as moduli of flat bundles on curves. The focus will be on non-abelian Hodge theory as a tool for implementing hyper Kaehler rotations of...

Congruences between motives and congruences between values of $L$-functions
Olivier Fouquet
4:30pm

If two motives are congruent, is it the case that the special values of their respective $L$-functions are congruent? More precisely, can the formula predicting special values of motivic $L$-functions be interpolated in $p$-adic families of motives...

Reading Group on Quantization of BCOV and the Higher-Genus B-Model

Givental's quantization of semi-simple Frobenius manifolds
4:00pm

Givental's quantization formula describes higher genus invariants from genus zero data, the Frobenius manifold. I will describe this quantization and state Teleman's result that this quantization actually describes all semisimple cohomological field...

Computing a categorical Gromov-Witten invariant
Andrei Căldăraru
1:00pm

In his 2005 paper "The Gromov-Witten potential associated to a TCFT" Kevin Costello described a procedure for recovering an analogue of the Gromov-Witten potential directly out of a cyclic A-inifinity algebra or category. Applying his construction...

Contact non-squeezing in $mathbb R^{2n} times S^1$ by other means
Maia Fraser
10:45am

In this talk, following right after Chiu's, I will summarize two other tools capable of detecting the non-squeezing property of pre-quantized balls in $\mathbb R^{2n} \times S^1$. One of these is a $\mathbb Z_k$-equivariant version of contact...
