February 24, 2022 1:00 pmThe spontaneous emergence of collective flows is a generic property of active fluids and often leads to chaotic flow patterns characterized by swirls, jets, and topological disclinations in their orientation...

February 22, 2022 9:30 amIn the study of Ising models on large locally tree-like graphs, in both rigorous and non-rigorous methods one is often led to understanding the so-called belief propagation distributional recursions and...

February 22, 2022 9:30 amWe construct a certain type of Gauged Linear Sigma Model quasimap invariants that generalize the original ones and are easier to compute. Higgs-Coulomb correspondence provides identification of generating functions of...

February 17, 2022 9:30 am't Hooft anomalies of anomalous systems can be described via anomaly inflow by invertible theories living in one dimension higher. Thanks to this it is possible to provide a general...

February 17, 2022 9:00 amFinite order Markov models are theoretically well-studied models for dependent data. Despite their generality, application in empirical work when the order is larger than one is quite rare. Practitioners avoid...

February 16, 2022 9:30 amIn 1960's, Narasimhan and Seshadri discovered the equivalence between irreducible unitary flat bundles and stable bundles of degree $0$ on compact Riemann surfaces. In 1980's, Donaldson, Uhlenbeck and Yau generalized it...

February 16, 2022 4:30 pmSuppose you write down a general polynomial in x, y, z and consider the surface of all points where it vanishes. What can you say about the family of lines...
