Singular control with state constraints on unbounded domain [PDF]

open access: yes, 2006
We study a class of stochastic control problems where a cost of the form \begin{equation}\mathbb{E}\int_{[0,\infty)}e^{-\beta s}[\ell(X_s) ds+h(Y^{\circ}_s) d|Y|_s]\end{equation} is to be minimized over control processes $Y$ whose increments take values ...

Unbounded domains of normality [PDF]

open access: yesProceedings of the American Mathematical Society, 1998
Let f f be a transcendental entire function of order less than 1/2. We introduce the method of “self-sustaining spread” to study the components of the set of normality of such a function. We give a new proof of the fact that any preperiodic or periodic component of the set of normality of f f is bounded.

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.

Dynamics of a time-periodic and delayed reaction-diffusion model with a quiescent stage

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
In this paper, we study a time-periodic and delayed reaction-diffusion system with quiescent stage in both unbounded and bounded habitat domains. In unbounded habitat domain $\mathbb{R}$, we first prove the existence of the asymptotic spreading speed and

The Dirichlet problem in an unbounded cone-like domain for second order elliptic quasilinear equations with variable nonlinearity exponent

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
In this paper we consider the Dirichlet problem for quasi-linear second-order elliptic equation with the $m(x)$-Laplacian and the strong nonlinearity on the right side in an unbounded cone-like domain.

Positive solutions to superlinear second-order divergence type elliptic equations in cone-like domains [PDF]

open access: yes, 2003
We study the problem of the existence and nonexistence of positive solutions to a superlinear second-order divergence type elliptic equation with measurable coefficients $(*)$: $-\nabla\cdot a\cdot\nabla u=u^p$ in an unbounded cone--like domain $G\subset\

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

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.
