Abstract:Let (X, L) be a polarized scheme over a Banach ring A. We define and study a class PSH(X, L) of plurisubharmonic metrics on the Berkovich analytification X an . We focus mainly on the case where A is a hybrid ring of power series, so that X an is the hybrid space associated to a degeneration of complex manifolds X. We then prove that any plurisubharmonic metric on (X, L) with logarithmic growth at zero admits a canonical plurisubharmonic extension to the hybrid space X hyb . We also discuss the continuity of t… Show more
