Commuting Toeplitz and Hankel Operators on Harmonic Dirichlet Spaces

Journal of Function Spaces, 2017
On the harmonic Dirichlet space of the unit disk, the commutativity of Toeplitz and Hankel operators is studied. We obtain characterizations of commuting Toeplitz and Hankel operators and essentially commuting (semicommuting) Toeplitz and Hankel ...

A mixed semilinear parabolic problem from combustion theory

Electronic Journal of Differential Equations, 2001
We prove existence, uniqueness, and regularity of the solution to a mixed initial boundary-value problem. The equation is semilinear uniformly parabolic with principal part in divergence form, in a non-cylindrical space-time domain.

Evans-Vasilesco theorem in Dirichlet spaces

Rendiconti di Matematica e delle Sue Applicazioni, 1999
After introducing the notion of weak solutions and the local Kato class associated with a regular Dirichlet form, the authors prove an estimate for the Green's function by using the assumed doubling property of the intrinsic balls. This estimate is used to extend the Evans-Vasilesco theorem on the continuity of the potential of a non-negative Radon ...

Boundedness and Compactness of Weighted Composition Operators From Banach Spaces of Holomorphic Functions to Weighted-Type Banach Spaces on the Polydisk

Journal of Function Spaces
In this work, we characterize the bounded and compact weighted composition operators from a large class of Banach space X of holomorphic functions on the open unit polydisk Dn into weighted-type Banach spaces of holomorphic functions on Dn.

On the regularity of elliptic differential equations using symmetry techniques and suitable discrete spaces

Electronic Journal of Differential Equations, 1996
second order elliptic differential equations with homogeneous Dirichlet boundary conditions. The proof uses a discrete function space with piecewise multilinear functions and symmetry techniques on the unit cube.

Fractional Sobolev space: Study of Kirchhoff-Schrödinger systems with singular nonlinearity

Cubo
This study extensively investigates a specific category of Kirchhoff-Schrödinger systems in fractional Sobolev space with Dirichlet boundary conditions. The main focus is on exploring the existence and multiplicity of non-negative solutions.

Vector Calculus for Tamed Dirichlet Spaces

Memoirs of the American Mathematical Society
In the language of L ∞ L^\infty -modules proposed by Gigli, we introduce a first order calculus on a topological Lusin measure space ( M , m ) (M,\mathfrak {m}) carrying a quasi-regular, strongly local Dirichlet form \usefont {U ...

New Well-Posed boundary conditions for semi-classical Euclidean gravity

Journal of High Energy Physics
We consider four-dimensional Euclidean gravity in a finite cavity. Dirichlet conditions do not yield a well-posed elliptic system, and Anderson has suggested boundary conditions that do.
