 WednesdayMarch 27, 20192:30 PM - 3:30 PM Math Tower P-131 Mini Course / Dynamics Learning SeminarJonathan Fraser, University of St Andrews Dimensions of Kleinian limit setsThe dimension theory of geometrically finite Kleinian groups and their limit sets has a rich and interesting history, with the first calculation of Hausdorff dimension going back to seminal work of Patterson and Sullivan from the 1970s and 80s. There are many different (but related) notions of dimension but, nevertheless, many of the most popular coincide in this setting. In particular, the Hausdorff, box-counting, and packing dimensions of a Kleinian limit set are all given by the Poincare exponent of the group. I will discuss recent work concerning the Assouad dimension, which is not necessarily given by the Poincare exponent in the presence of parabolic points.

 WednesdayApril 03, 20192:30 PM - 3:30 PM Math Tower P-131 Mini Course / Dynamics Learning SeminarMalik Younsi, University of Hawaii TBATBA

 WednesdayApril 03, 20194:00 PM - 5:00 PM TBA Simons Lectures SeriesAlex Eskin, University of Chicago Polygonal billiards and dynamics on moduli spaces of compact Riemann surfacesBilliards in polygons can exhibit some bizarre behavior, some of which can be explained by deep connections to several seemingly unrelated branches of mathematics. These include algebraic geometry (and in particular Hodge theory), Teichmuller theory and ergodic theory on homogeneous spaces. I will attempt to give a gentle introduction to the subject. Much of this lecture will be accessible to undergraduates and first-year graduate students.

 WednesdayApril 03, 20192:30 PM - 3:30 PM Math Tower P-131 Algebraic geometry seminarIgnacio Barros, Northeastern University Two moduli spaces of Calabi-Yau type.(Note special time due to Simons lectures) For fixed genus $g$, the transition of $\mathcal{M}_{g,n}$ from uniruled to general type as $n$ increases is rather sudden, making the cases of intermediate Kodaira dimension very rare. In genus $4≤ g ≤ 11$ there are just a few cases for which we still don't know the Kodaira dimension of $\mathcal{M}_{g,n}$, some of them with very rich geometries. I will report on work-in-progress with Scott Mullane, where we study some of this cases hoping to find more instances of intermediate Kodaira dimension.

 ThursdayApril 04, 20192:30 PM P-131 Analysis SeminarMichael Damron, Georgia Tech TBATBA

 ThursdayApril 04, 20194:00 PM - 5:00 PM TBA Simons Lectures SeriesAlex Eskin, University of Chicago The classification of invariant measuresRatner's celebrated theorems on unipotent flows in homogeneous spaces have partial analogues in moduli space. I will outline the proof (joint with Maryam Mirzakhani and in part Amir Mohammadi) of one such theorem.

 FridayApril 05, 20194:00 PM - 5:00 PM TBA Simons Lectures SeriesAlex Eskin, University of Chicago Orbit closures: theorems and counterexamplesIn this lecture I will survey some of what is currently known about the classification of SL(2,R) orbit closures, and complete the proof of some results from Lecture 1. This lecture will have a more algebraic flavor than the others.

 ThursdayApril 11, 20194:00 PM - 5:00 PM Math Tower P-131 ColloquiumErnest Croot, Georgia Tech Long Progressions in SumsetsAn old question in additive number theory is determining the length of the longest progression in a sumset A+B = {a + b : a in A, b in B}, given that A and B are "large" subsets of {1,2,...,n}. I will survey some of the results on this problem, including a discussion of the methods, and also will discuss some open questions and conjectures.

 TuesdayApril 16, 20194:00 PM - 5:00 PM Math Tower P-131 Geometry/Topology SeminarFedor Manin, Ohio State University Rational homotopy and topological isoperimetrySoon after Sullivan introduced his model of rational homotopy theory in the 1970's, Gromov noted that the theory had some metric consequences for maps between compact manifolds or simplicial complexes. I will present a systematic view of this relationship which gives a powerful tool for, among other things, resolving the following type of question, asked by Gromov twenty years later: Given two $L$-Lipschitz maps $f, g: X → Y$, where $X$ and $Y$ are nice compact metric spaces, what is the optimal Lipschitz constant of a homotopy between them? I will also try to explain why this question is fundamental to quantitative topology.

 ThursdayApril 18, 20192:30 PM P-131 Analysis SeminarAntonio De Rosa, NYU Anisotropic counterpart of Allard’s rectifiability theorem and Plateau problem.We present our extension of Allard's celebrated rectifiability theorem to the setting of varifolds with locally bounded anisotropic first variation. We identify a necessary and sufficient condition on the integrand for its validity and we discuss the connections of this condition to Almgren's ellipticity. We apply this result to the set-theoretic anisotropic Plateau problem, obtaining solutions to three different formulations: one introduced by Reifenberg, one proposed by Harrison and Pugh and another one studied by David. Moreover, we apply the rectifiability theorem to prove an anisotropic counterpart of Allard's compactness result for integral varifolds. Some of the presented theorems are joint works with De Lellis, De Philippis, Ghiraldin and Kolasiński

 ThursdayApril 25, 20192:30 PM P-131 Analysis SeminarVladimir Bozin, University of Belgrade Quasiconformal harmonic maps and the bi-Lipschitz conditionWe discuss some recent results regarding the Euclidean quasiconformal harmonic maps. In particular, we show, using the Gehring-Osgood inequality, that quasiconformal maps between plane domains with $C^{1,α}$ boundary are bi-Lipschitz. We will also discuss questions related to the boundary behavior of hqc maps and generalizations to the higher dimensional case.
