Prof. Marcelo Disconzi appears at Parnassus Bookstore
Nov. 24, 2024—Professor Marcelo Disconzi appeared at a meet-the-author event, discussing his book “I’m a Mathematician Now!” The event was held on October 21, 2024 at the Parnassus Bookstore in Green Hills, the flagship bookstore owned by famed author Ann Patchett. Prof. Disconzi appeared alongside Prof. Larisa DeSantis, Associate Professor in the Departments of Biological Sciences and...
Colloquium – Talk by Dick Canary: November 22, 2024
Nov. 22, 2024—November 22, 2024 (Friday), 4:10 p.m. Dick Canary, University of Michigan An invitation to Anosov representations Fuchsian groups arise naturally as groups of covering transformations of hyperbolic surfaces. One may view them as images of discrete faithful representation of free groups and surface groups into PSL(2,R). The study of hyperbolic surfaces and deformation spaces of...
Prof. Dan Margalit and Isaiah Williams ’25 Unravel Mysteries of Math
Nov. 17, 2024—A new video made by the College of Arts & Science communications team aims to answer some of the frequently searched questions about mathematics. Prof. Dan Margalit, Chair of Mathematics and Stevenson Chair, along with undergraduate Isaiah Williams, class of ’25 fielded questions and answered them in the madcap video made by Liz Chagnon. The...

Nov. 15, 2024—AU-Acylindricity in Higher Rank, and its Accompanying (Imperfect) Semi-Simple Dictionary – Location- SC1432 November 15, 2024 (Friday), 4:10 pm Talia Fernós, University of North Carolina, Greensboro AU-Acylindricity may be viewed as generalizing the type of action a lattice enjoys on its ambient space. In a recent joint work with S. Balasubramanya, we extend the theory...
Geometry and Topology Seminar: November 8, 2024
Nov. 8, 2024—Speaker: Valentina Zapata Castro (University of Virginia) Title: A monoid can be interpreted as a category with a single object, where the morphisms correspond to the elements of the monoid. Extending this concept to higher categories, in this talk I will explore the relationship between complete Segal spaces with a monoidal structure and complete Segal Theta_2-spaces, considering an approach...
Colloquium – Talk by Jean-Francois Paquet: November 7, 2024
Nov. 7, 2024—November 7, 2024 (Thursday), 4:10 p.m. Jean-Francois Paquet, Vanderbilt University Special relativity meets fluid dynamics: the transformative role of nucleus colliders Quark-gluon plasma is an exotic phase of nuclear matter that can be produced by colliding large nuclei at velocities close to the speed of light. This plasma is the smallest and hottest liquid ever...

Colloquium – Detection and characterization of chirps and oscillating singularities in datas: October 31, 2024
Oct. 31, 2024—October 31, 2024 (Thursday), 4:10 p.m. Stephane Jaffard- University Paris Est Creteil Many types of signals display a very oscillatory behavior in the neighborhood of singularities. It is for example the case for gravitational waves, fully developed turbulence, or brain data. A major issue is to detect such behaviors (referred to as “oscillating singularities” or...
Geometry and Topology Seminar: October 25, 2024
Oct. 25, 2024—Speaker: Yifan Chen (UC Berkeley) Title: More Complete Calabi-Yau Metrics of Calabi Type Abstract: We construct more complete Calabi-Yau metrics asymptotic to Calabi ansatz. They are the higher-dimensional analogues of ALH* gravitational instantons in two dimensions. Our work builds on and generalizes the results of Tian-Yau and Hein-Sun-Viaclovski-Zhang, creating Calabi-Yau metrics that are only polynomially close to the model...
Colloquium – Curve graphs and totally geodesic subvarieties of moduli spaces of Riemann surfaces: October 24, 2024
Oct. 24, 2024—October 24, 2024 (Thursday), 4:10 p.m. Alex Wright- University of Michigan Given a surface, the associated curve graph has vertices corresponding to certain isotopy classes of curves on the surface, and edges for disjoint curves. Starting with work of Masur and Minsky in the late 1990s, curve graphs became a central tool for understanding objects...
