MATH - Seminar on Pure Mathematics - Counting sheaves on Calabi-Yau 4-folds
We define a localised Euler class for isotropic sections, and isotropic cones, in SO(N) bundles. We use this to give an algebraic definition of Borisov-Joyce's sheaf counting invariants on Calabi-Yau 4-folds.

MATH - Seminar on Data Science - Compression and Acceleration of Pre-trained Language Models
Recently, pre-trained language models based on the Transformer structure like BERT and RoBERTa have achieved remarkable results on various natural language processing tasks and even some computer vision tasks.

MATH - Seminar on Pure Mathematics - Cluster structurer on K-theoretic Coulomb branches, part II.
It was conjectured by Davide Gaiotto, that K-theoretic Coulomb branches of 3d N=4 SUSY gauge theories possess structure of cluster varieties. In this talk, I will explain how to attack this conjecture in the case of quiver gauge theories.
