Translation functors, branching problems, and applications to the restriction of coherent cohomology of Shimura varieties

Michael Harris, Toshiyuki Kobayashi, Birgit Speh

We study properties of the restriction of discrete series representations of G=U(p,q) to G′=U(p−1,q) and the corresponding symmetry breaking operators in $\operatorname{Hom}_{…

math.RT2025

How does the restriction of representations change under translations? A story for the general linear groups and the unitary groups

Toshiyuki Kobayashi, Birgit Speh

We present a new approach to symmetry breaking for pairs of real forms of (GL(n,C),GL(n−1,C)). Translation functors are powerful tools for studying families…
