Bergman completeness of unbounded hartogs Domains [PDF]

open access: yesNagoya Mathematical Journal, 2005
AbstractSome results for the Bergman functions in unbounded domains are shown. In particular, a class of unbounded Hartogs domains, which are Bergman complete and Bergman exhaustive, is given.

Uniform boundedness and extinction results of solutions to a predator–prey system

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
Global existence, positivity, uniform boundedness and extinction results of solutions to a system of reaction-diffusion equations on unbounded domain modeling two species on a predator–prey relationship is considered.

A natural boundary element method for the Sobolev equation in the 2D unbounded domain

open access: yesBoundary Value Problems, 2017
In this article, we devote ourselves to establishing a natural boundary element (NBE) method for the Sobolev equation in the 2D unbounded domain. To this end, we first constitute the time semi-discretized super-convergence format for the Sobolev equation

The essential numerical range for unbounded linear operators [PDF]

open access: yes, 2020
We introduce the concept of essential numerical range W_e(T) for unbounded Hilbert space operators T and study its fundamental properties including possible equivalent characterizations and perturbation results.

Conditional Expectations for Unbounded Operator Algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
Two conditional expectations in unbounded operator algebras (O∗-algebras) are discussed. One is a vector conditional expectation defined by a linear map of an O∗-algebra into the Hilbert space on which the O∗-algebra acts.

Boundary-domain integral equations for variable coefficient Dirichlet BVP in 2D unbounded domain [PDF]

open access: yes, 2019

A Domain Decomposition Method Based on Natural BEM and Mixed FEM for Stationary Stokes Equations on Unbounded Domains

open access: yes, 2012
In this paper, a new domain decomposition method is suggested for the stationary Stokes equations on unbounded domain and its convergence is proved. We draw an artificial boundary to make the domain into two parts: one is bounded, in which we use the ...
