Roughly, this conjecture says that branching laws for $U(n-1)\subset U(n)$ can be computed using epsilon factors. %G French %2 https://hal.science/hal-00761084v2/document %2 https://hal.science/hal-00761084v2/file/endoscopieGPcorrected.pdf %L hal-00761084 %U https://hal.science/hal-00761084 %~ UNIV-PARIS7 %~ UPMC %~ CNRS %~ IMJ %~ UPMC_POLE_1 %~ SORBONNE-UNIVERSITE %~ SU-SCIENCES %~ UNIV-PARIS %~ UP-SCIENCES %~ SU-TI %~ ALLIANCE-SU
