Covariant representations of algebraic group actions and applications
Yvann Gaudillot-Estrada
If is an algebraic affine group acting on an affine variety , there is a natural notion of covariant representation for the pair . In this paper, we classify the irre…
The smallest quantum Mackey deformation
Yvann Gaudillot-Estrada
When is a real semisimple group, there is a surprising interplay between its representation theory and that of its motion group , known as the Mackey analogy. The present…
A non-unitary approach to the -deformation of
Yvann Gaudillot-Estrada
We study the representation theory of various convolution algebras attached to the -deformation of from an algebraic perspective and beyond the unita…
Convergence of spectral truncations for compact metric groups
Yvann Gaudillot-Estrada, Walter D. van Suijlekom
We consider Gromov-Hausdorff convergence of state spaces for spectral truncations of a compact metric group . We work in the context of order-unit spaces and consider orthogonal…
