【摘要】
Multiplier ideal sheaves with line bundles have played an important role and been well-studied in complex geometry. For general vector bundles, we consider the L^2 multiplier submodule sheaf associated to a singular Hermitian metric, defined by M. A. de Cataldo. we obtain a Le Potier-type isomorphism theorem twisted with multiplier submodule sheaves, which relates a holomorphic vector bundle endowed with a strongly Nakano semipositive singular Hermitian metric to the tautological line bundle with the induced metric. As applications, we obtain a Kollár-type injectivity theorem, a Nadel-type vanishing theorem, and a singular holomorphic Morse inequality for holomorphic vector bundles and so on.
