LOCAL SYSTEMS ON COMPLEMENTS OF ARRANGEMENTS OF SMOOTH, COMPLEX ALGEBRAIC HYPERSURFACES

open access: yesForum of Mathematics, Sigma, 2018
We consider smooth, complex quasiprojective varieties $U$ that admit a compactification with a boundary, which is an arrangement of smooth algebraic hypersurfaces. If the hypersurfaces intersect locally like hyperplanes,

Cohomology with bounds and Carleman estimates for the ∂¯-operator on Stein manifolds

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
Cohomology with bounds are used to globalize a result of Hörmander obtaining Carleman estimates for the Cauchy-Riemann operator on Stein manifolds.

Compactness of the Complex Green Operator on C1 Pseudoconvex Boundaries in Stein Manifolds

open access: yesMathematics
We study compactness for the complex Green operator Gq associated with the Kohn Laplacian □b on boundaries of pseudoconvex domains in Stein manifolds. Let Ω⋐X be a bounded pseudoconvex domain in a Stein manifold X of complex dimension n with C1 boundary.

Approximation and extension of Hermitian metrics on holomorphic vector bundles over Stein manifolds

open access: yesComptes Rendus. Mathématique
We show that a singular Hermitian metric on a holomorphic vector bundle over a Stein manifold which is negative in the sense of Griffiths (resp. Nakano) can be approximated by a sequence of smooth Hermitian metrics with the same curvature negativity.

A Sheaf-Theoretic CR Reduction for Levi-Flat Manifolds Beyond the Kähler Setting

open access: yesInternational Journal of Mathematics and Mathematical Sciences
This paper develops a sheaf-theoretic reduction formalism for real-analytic homogeneous CR manifolds realized as orbits in complex homogeneous manifolds.

Comparing three possible hypoelliptic Laplacians on the 5-dimensional Cartan group via div-curl type estimates

open access: yesAdvanced Nonlinear Studies
On general Carnot groups, the definition of a possible hypoelliptic Hodge-Laplacian on forms using the Rumin complex has been considered in (M. Rumin, “Differential geometry on C-C spaces and application to the Novikov-Shubin numbers of nilpotent Lie ...
