Motivic cohomology of cyclic coverings | BIMSA-YMSC AG Seminar

Abstract Many examples of topologically contractible smooth affine complex varieties are given by cyclic coverings. In this talk, we explain some new results on the motivic cohomology of such cycli...

Game Theory Seminar | The statistical topology theory of aging

Abstract The traditional view suggests that aging is a progressive decline of physiological and physical function with passage of time. However, increasing evidence shows that aging may be subject

One- and two-dimensional higher-point conformal blocks as free-particle wavefunctions in AdS$_3

Abstract We establish that all of the one- and two-dimensional global conformal blocks are, up to some choice of prefactor, free-particle wavefunctions in tensor products of AdS$_3$ or limits

Wild automorphisms of compact complex spaces

Abstract An automorphism of a compact complex space is called wild if there is no non-trivial proper invariant analytic subset. In this talk, I will show that a compact complex surface admitting

Relative entropy for quantum channels | BIMSA-Tsinghua Quantum Symmetry Seminar

Abstract We introduce an quantum entropy for bimodule quantum channels on finite von Neumann algebras, generalizing the remarkable Pimsner-Popa entropy. The relative entropy for Fourier multipliers

Caltech-Tsinghua Joint Colloquium | Irregular conformal blocks and braiding properties

Abstract In this talk, I would like to report our recent work arXiv: 2301.07957 & 2311.07960. We constructed the rank-1 irregular field in the free boson theory and computed the conformal blocks wi
