 Month Agenda

 TuesdayOctober 17, 20174:00 PM - 5:00 PM Math Tower P-131 Geometry/Topology SeminarJiyuan Han, UW-Madison On closedness of ALE SFK metrics on minimal ALE Kahler surfacesFor certain cases with some topological assumption that gives the boundedness of Sobolev constant, we construct the space of ALE SFK metrics on minimal ALE Kahler surfaces asymptotic to C^2/G, where G is a finite subgroup of U(2). This is a joint work with Jeff Viaclovsky.

 WednesdayOctober 18, 20171:00 PM Math Tower 4-130 Math ClubArie Hinkis, How can mathematical proofs be compared ?The Cantor-Bernstein Theorem received the attention of over forty proofs in the first hundred years since it was formulated. We offer a method for the comparison of these proofs. The method reveals a general pattern for the discovery of proofs in mathematics. We draw attention to the inner history of mathematics regarding the seminal work of Denes Koenig on the theory of graphs and mention in passing several historical anecdotes.

 WednesdayOctober 18, 20174:00 PM - 5:00 PM Math Tower P-131 Algebraic geometry seminarHarold Blum, U. Michigan, Ann Arbor Valuations, Singularities, and K-stabilityLet L be a line bundle on a projective variety X. We use valuations to measure the singularities of the linear system |mL| as m goes to infinity. Specifically, we consider the global log canonical threshold, also known as Tian’s alpha invariant, and the stability thresholds of L. The stability threshold generalizes an invariant recently introduced by Kento Fujita and Yuji Odaka. When X is a Fano variety, we show that the stability threshold detects the K-(semi)stability of X. This talk is based on joint work with Mattias Jonsson.

 ThursdayOctober 19, 20174:00 PM - 5:00 PM Math Tower P-131 ColloquiumAlex Gamburd, CUNY Graduate Center Arithmetic and Dynamics on Markoff-Hurwitz VarietiesMarkoff triples are integer solutions of the equation $x^2+y^2+z^2=3xyz$ which arose in Markoff's spectacular and fundamental work (1879) on diophantine approximation and has been henceforth ubiquitous in a tremendous variety of different fields in mathematics and beyond. After reviewing some of these, we will discuss joint work with Bourgain and Sarnak on the connectedness of the set of solutions of the Markoff equation modulo primes under the action of the group generated by Vieta involutions, showing, in particular, that for almost all primes the induced graph is connected. Similar results for composite moduli enable us to establish certain new arithmetical properties of Markoff numbers, for instance the fact that almost all of them are composite. Time permitting, we will also discuss recent joint work with Magee and Ronan on the asymptotic formula for integer points on Markoff-Hurwitz surfaces $x_1^2+x_2^2 + \dots + x_n^2 = x_1 x_2 \dots x_n$, giving an interpretation for the exponent of growth in terms of certain conformal measure on the projective space.

 FridayOctober 20, 20172:30 PM - 3:30 PM Math Tower P-131 Dynamical Systems SeminarYury Kudryashov, Cornell University Bifurcations of planar vector fieldsIn 1985 V. Arnold stated six problems aimed to outline the future development of the global bifurcation theory in the plane. In particular, he conjectured that a generic finite-parametric family of vector fields on the two-sphere is structurally stable. Recently Yulij Ilyashenko, Ilya Schurov and I disproved this conjecture [1]. It turns out that 3-parametric families of vector fields may have numerical invariants of (moderate) topological classification, and 6-parametric families may have functional invariants. I will discuss the main construction of [1], then I'll give a survey of the results obtained by Yu. Ilyashenko and his students N. Goncharuk, me, I. Schurov, N. Solodovnikov, V. Starichkova. I will also discuss some ongoing research in this field that may lead to many independent numerical invariants of the 3-parametric family of vector fields constructed in [1].

 TuesdayOctober 24, 20175:25 PM - 6:30 PM Math Tower 5-127 First and Second Year Student SeminarPanel discussion, Stony Brook University Prepare qual/comps We will hold a discussion session with Ben Wu, Tobias Shin, Liz Hernandez Vazquez, and Aleksandar Milivojevic about preparing/taking qual/comps.

 TuesdayOctober 24, 20174:00 PM - 5:30 PM Math Tower P-131 Geometry/Topology SeminarMark Haskins, University of Bath Codimension One Collapse and Special Holonomy MetricsIn this talk we describe recent developments related to codimension one collapse of exceptional holonomy metrics. i.e. where a family of special holonomy metrics on a space of dimension n converges in some limit to a metric on a space of dimension n-1. Interesting examples occur for hyperkaehler 4-manifolds, G_2 holonomy manifolds and Spin_7 holonomy manifolds. The talk will focus on the G_2 holonomy case, but will also draw on the better understood hyperkaehler case for inspiration and for useful analogies. These mathematical developments are closely related to important limits in physics, e.g. in the context of G_2 holonomy metrics it is related to the identification of the weak coupling limit of M theory compactified on a G_2 holonomy space being Type IIA String Theory on a 6-dimensional space. This is work joint with Lorenzo Foscolo and Johannes Nordstrom.

 FridayOctober 27, 20172:30 PM - 3:30 PM Math Tower P-131 Dynamical Systems SeminarBabak Modami, Stony Brook University Renormalization in Teichmuller dynamicsAfter a brief review of Masur's criterion which is an example of the renormalization technique in Teichmuller dynamics, we show that an analogue of the criterion does not hold for the Weil-Petersson geodesic flow. The talk is based on a joint work with Jeff Brock from 2015.

 MondayOctober 30, 20174:00 PM - 5:30 PM Math Tower P-131 Special Algebra / Algebraic Geometry SeminarRemy van Dobben de Bruyn, Columbia University Dominating varieties by liftable ones.Given a smooth projective variety over an algebraically closed field of positive characteristic, can we always dominate it by another smooth projective variety that lifts to characteristic 0? We give a negative answer to this question.
