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. When a torus acts, we prove a localisation result. This talk is based on the joint work with Richard. P. Thomas.

IAS / School of Science Joint Lecture - Molecular Basis of Wnt Biogenesis, Secretion and Ligand Specific Signaling
Abstract
Wnt signaling is essential to regulate embryonic development and adult tissue homeostasis. Aberrant Wnt signaling is associated with cancers. The ER-resident membrane-bound O-acyltransfera...

IAS / School of Science Joint Lecture - Understanding the Roles of Transposable Elements in the Human Genome
Abstract
Transposable elements (TEs) have expanded the binding repertoire of many transcription factors and, through this process, have been co-opted in different transcriptional networks. In this ...
