We consider a domain Ω with Lipschitz boundary, which is relatively compact in ann-dimensional Kähler manifold and satisfies some “logδ-pseudoconvexity” condition. We show that the\(\bar \partial \)-equation with exact support in ω admits a solution in bidegrees (p, q), 1≤q≤n?1. Moreover, the range of\(\bar \partial \) acting on smooth (p, n?1)-forms with support in\(\bar \Omega \) is closed. Applications are given to the solvability of the tangential Cauchy-Riemann equations for smooth forms and currents for all intermediate bidegrees on boundaries of weakly pseudoconvex domains in Stein manifolds and to the solvability of the tangential Cauchy-Riemann equations for currents on Levi flatCR manifolds of arbitrary codimension. 相似文献

We use the semiclassical
-dressing method to derive compact generating equations for dispersionless hierarchies. The considered illustrative examples are the dispersionless Kadomtsev–Petviashvili and two-dimensional Toda lattice hierarchies. 相似文献

It is shown that every solution to the equation $
X\bar X = \bar XX
$
X\bar X = \bar XX
can be reduced by a real orthogonal similarity transformation to a block triangular form with diagonal blocks of orders one
and two. If the solution X is a normal matrix, then its block triangular form is actually a block diagonal. In this case, the form of the diagonal blocks
is found, yielding new proof of the recent results of Goodson and Horn. 相似文献

A horizontal\(\bar \partial \)-Laplacian is defined on strongly pseudoconvex complex Finsler manifolds, first for functions and then for horizontal differential forms of type (p, q). The principal part of the\(\bar \partial \)-Laplacian is computed in local coordinates. As an application, the\(\bar \partial \)-Laplacian on strongly Kähler Finsler manifold is obtained explicitly in terms of the horizontal covariant derivatives of the Chern-Finsler conncetion.

We consider the solution operator S: ℱμ,(p,q) → L
2(μ)(p, q) to the
-operator restricted to forms with coefficients in ℱμ = {f: f is entire and ∫ℂn
|f(z)|2 dμ(z) < ∞}. Here ℱμ,(p,q) denotes (p,q)-forms with coefficients in ℱμ, L
2(μ) is the corresponding L
2-space and μ is a suitable rotation-invariant absolutely continuous finite measure. We will develop a general solution formula
S to
. This solution operator will have the property Sv ⊥ ℱ(p,q) ∀v ∈ ℱ(p,q+1). As an application of the solution formula we will be able to characterize compactness of the solution operator in terms
of compactness of commutators of Toeplitz-operators

The homotopy formulas of (r, s) differential forms and the solution of $\bar \partial $ -equation of type (r, s) on localq-convex domains in Stein manifolds are obtained. The homotopy formulas on localq-convex domains have important applications in uniform estimates of $\bar \partial $ -equation and holomorphic extension of CR-manifolds. 相似文献

We present a construction of globally convergent power series of integrable Beltrami differentials on the Ricci-flat \(\partial \overline \partial \)-manifolds and also a construction of global canonical family of holomorphic (n, 0)-forms on the deformation spaces of the Ricci-flat \(\partial \overline \partial \)-manifolds. 相似文献

This paper concernsL ∞-variants of Hörmanders weightedL 2-estimates for the $\bar \partial - equation$ . In particular, we discuss a conjecture concerning suchL ∞-estimates which is related to the corona problem in the ball, and show a weaker version of this conjecture. The proof uses a refinedL 2-estimate for the canonical solution to the $\bar \partial - equation$ . An alternative approach based on von Neumann’s Minimax theorem is also given. 相似文献
