Topological Classification of Symmetry Breaking and Vacuum Degeneracy

Simon-Raphael Fischer, Mehran Jalali Farahani, Hyungrok Kim +1

We argue that a general system of scalar fields and gauge fields manifesting vacuum degeneracy induces a principal groupoid bundle over spacetime and that the pattern of spontaneou…

Adjusted Connections I: Differential Cocycles for Principal Groupoid Bundles with Connection

Simon-Raphael Fischer, Mehran Jalali Farahani, Hyungrok Kim +1

We develop a new perspective on principal bundles with connection as morphisms from the tangent bundle of the underlying manifold to a classifying dg-Lie groupoid. This groupoid ca…

A classification of neighborhoods around leaves of a singular foliation

Simon-Raphael Fischer, Camille Laurent-Gengoux

We classify singular foliations admitting a given leaf and a given transverse singular foliation.
