Asymptotics for Bergman-Hodge kernels for high powers of complex line bundles

Robert Berman, Johannes Sjoestrand

In this paper we obtain the full asymptotic expansion of the Bergman-Hodge kernel associated to a high power of a holomorphic line bundle with non-degenerate curvature. We also exp…

Fractal upper bounds on the density of semiclassical resonances

J. Sjoestrand, M. Zworski

For semiclassical problems we establish upper bounds on the number of resonances in boxes of size h along the real axis, in terms of the dimension of the set of trapped trajector…

Asymptotics of Bergman kernels

Robert Berman, Bo Berndtsson, Johannes Sjoestrand

We give an elementary proof of the existence of an asymptotic expansion in powers of k of the Bergman kernel associated to Lk, where L is a positive line bundle. We also giv…
