Dear all,

We would like to announce that Juan Orendain (Universidad Nacional 
Autonoma de Mexico-UNAM)
will give a talk in the "Higher Structures Webinars" of Feza Gürsey 
Center for Physics and
Mathematics.

TITLE: "Higher lattice gauge fields and cubical \omega-groupoids"
ABSTRACT: Gauge fields describe parallel transport of point particles 
along curves, with respect to connections on principal bundles. This 
data is captured as a smooth functor from the smooth path groupoid of 
the base manifold into the delooping groupoid of the structure group, 
plus gluing data. Lattice gauge fields do this for discretized versions 
of a base manifold. A lattice gauge field is thus a functor from a 
discrete version of the path groupoid to a delooping groupoid. Lattice 
gauge fields are meant to serve as discrete approximations of regular 
gauge fields.

Higher gauge fields describe parallel transport of curves along 
surfaces, of surfaces along volumes, etc. Several versions of 
2-dimensional gauge field have appeared in the literature. I will 
explain how to extend these ideas to lattice gauge fields on all 
dimensions, using Brown's cubical homotopy \omega-groupoid construction 
associated to filtered spaces, implementing a discrete notion of thin 
homotopy along the way.
