Given a Hodge manifold, it is introduced a self-adjoint operator on the space of endomorphisms of the global holomorphic sections of the polarization line bundle. Such operator is shown to approximate the Laplace operator on functions when composed with Berezin-Toeplitz quantization map and its adjoint, up to an error which tends to zero when taking higher powers of the polarization line bundle.
Let be a holomorphic differential operator acting on sections of a holomorphic vector bundle on an -dimensional compact complex manifold. We prove a formula, conjectured by Feigin and Shoikhet, giving the Lefschetz number of as the integral over the manifold of a differential form. The class of this differential form is obtained via formal differential geometry from the canonical generator of the Hochschild cohomology of the algebra of differential operators on a formal neighbourhood of a...
On a real hypersurface in of class we consider a local CR structure by choosing complex vector fields in the complex tangent space. Their real and imaginary parts span a -dimensional subspace of the real tangent space, which has dimension If the Levi matrix of is different from zero at every point, then we can generate the missing direction. Under this assumption we prove interior a priori estimates of Schauder type for solutions of a class of second order partial differential equations...
It is known that the fundamental solution to an elliptic differential equation with analytic coefficients exists, is determined up to the kernel of the differential operator, and has singularities on characteristics of the equation in ℂ2. In this paper we construct a representation of fundamental solution as a sum of functions, each of those has singularity on a single characteristic.

Let be an irreducible Hermitian symmetric space of noncompact type. We study a -
invariant system of differential operators on called the Hua system. It was proved
by K. Johnson and A. Korányi that if is a Hermitian symmetric space of tube type,
then the space of Poisson-Szegö integrals is precisely the space of zeros of the Hua
system. N. Berline and M. Vergne raised the question about the nature of the common
solutions of the Hua system for Hermitian symmetric spaces of nontube type. In...
