INFORMAL GEOMETRY AND DYNAMICS
April 29, 2020 4:00 pmTriangulated surfaces are compact (hyperbolic) Riemann surfaces that admit a conformal triangulation by equilateral triangles. Brooks and Makover started the study of the geometry of random large genus triangulated surfaces. Mirzakhani...

April 29, 2020 2:00 pmSpin wave theory suggests that low temperature properties of the Heisenberg model can be described in terms of noninteracting quasiparticles called magnons. In my talk I will review the basic...

April 29, 2020 10:30 amI will give an account of the work ArXiv:1907.08221 where we explore the phase structure of the Standard Model as the relative strengths of the SU(2) weak force and SU(3)...

DIFFERENTIAL GEOMETRY
April 28, 2020 3:00 pmThe SYZ conjecture predicts that for polarised Calabi-Yau manifolds undergoing the large complex structure limit, there should be a special Lagrangian torus fibration. A weak version asks if this fibration...

April 28, 2020 10:00 amExperimentalists are getting better and better at building qubits, but no matter how hard they try, their qubits will never be perfect. In order to build a large quantum computer, we...

April 27, 2020 12:00 pmwill speak on: It is conjectured that two cubic fourfolds are birational if their associated K3 categories are equivalent. We prove this conjecture for very general cubic fourfolds of discriminant...

April 23, 2020 10:30 amThe most puzzling aspect of the `strange metal' behavior of correlated electron compounds is that the linear in temperature resistivity often extends down to low temperatures, lower than natural microscopic...

INFORMAL GEOMETRY AND DYNAMICS
April 22, 2020 4:00 pmWe give a construction of a pseudo-Anosov map of a surface starting from (and almost isomorphic to) a hyperbolic automorphism of an n-torus. The construction arises from a peano curve...

RANDOM MATRIX
April 22, 2020 2:00 pmWe introduce a class of UV-regularized two-body interactions for fermions in $\R^d$ and prove a Lieb-Robinson estimate for the dynamics of this class of many-body systems. As a step towards...

April 22, 2020 10:30 amGlobal anomalies in gauge theories are detected by the exponentiated eta-invariant, which becomes a cobordism invariant when perturbative anomalies vanish. We analyse global anomalies in four distinct (but equally valid)...
