Abstract

Let E be a Hermitian vector bundle over a complete Kähler manifold (X, ω), dimX = n, with a d(bounded) Kähler form ω, and let dA be a Hermitian connection on E. The goal of this article is to study the L2-Hodge theory on the vector bundle E. We extend the results of Gromov [18] to the Hermitian vector bundle. Finally, as an application, we prove a gap result for the Yang-Mills connection on the bundle E over X.

We would like to thank M. Gromov for kind comments regarding his article [18]. We would also like to thank an anonymous referee for careful reading of my manuscript and helpful comments. In particular, the referees pointed out that we can study the nonvanishing theorem in the small enough L-norm case.
