Isotopy invariance and stratified -structure of the Ran Grassmannian
Guglielmo Nocera, Morena Porzio
Let be a complex reductive group. A folklore result asserts the existence of an -algebra structure on the Ran Grassmannian of over …

A model for the assembly map of bordism-invariant functors
Jordan Levin, Guglielmo Nocera, Victor Saunier
We study oplax colimits of stable categories, of hermitian categories and of Poincaré categories in nice cases. This allows us to produce a categorical model of the assembly map o…

A model for the E3 fusion-convolution product of constructible sheaves on the affine Grassmannian
Guglielmo Nocera
Let be a complex reductive group. The spherical Hecke category of can be presented as the category of -equivariant constructible sheaves on the affine Grass…
