Plus/Minus $p$-adic $L$-functions for ${\mathrm{GL}}_{2n}$

Abstract

We generalise Pollack's construction of plus/minus L-functions to certain cuspidal automorphic representations of ${\mathrm{GL}}_{2n}$ using the $p$-adic $L$-functions constructed in forthcoming work of Barrera, Dimitrov and Williams.
