Large Time Decay of Solutions to a Linear Nonautonomous System in Exterior Domains

open access: yesMathematics, 2021
In this expository paper, we study Lq-Lr decay estimates of the evolution operator generated by a perturbed Stokes system in n-dimensional exterior domains when the coefficients are time-dependent and can be unbounded at spatial infinity.

Remark on upper bound for lifespan of solutions to semilinear evolution equations in a two-dimensional exterior domain [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 2017
In this paper we consider the initial-boundary value problem for the heat, damped wave, complex-Ginzburg-Landau and Schr"odinger equations with the power type nonlinearity $|u|^p$ with $p in (1,2]$ in a two-dimensional exterior domain. Remark that $2=1+2/

Global spherically symmetric flows for a viscous radiative and reactive gas in an exterior domain

open access: yesJournal of Differential Equations, 2019
We consider the equations for a viscous, compressible, radiative and reactive gas (pressure P = R ρ θ + a θ 4 / 3 , internal energy e = c v θ + a θ 4 / ρ ) over an unbounded exterior domain in R n , where n ≥ 2 is the space dimension.

Discrete exterior geometry approach to structure-preserving discretization of distributed-parameter port-Hamiltonian systems [PDF]

open access: yes, 2011
This paper addresses the issue of structure-preserving discretization of open distributed-parameter systems with Hamiltonian dynamics. Employing the formalism of discrete exterior calculus, we introduce a simplicial Dirac structure as a discrete analogue

Positive evanescent solutions of singular elliptic problems in exterior domains

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
We investigate the existence of positive solutions for the following class of nonlinear elliptic problems \[\operatorname{div}(a(\|x\|)\nabla u(x))+f(x,u(x))-(u(x))^{-\alpha}\|\nabla u(x)\|^{\beta}+g(\|x\|)x\cdot\nabla u(x)=0,\] where $x\in\mathbb{R}^{n}$

Solvability of Iterative Classes of Nonlinear Elliptic Equations on an Exterior Domain

open access: yesAxioms, 2023
This work explores the possibility that iterative classes of elliptic equations have both single and coupled positive radial solutions. Our approach is based on using the well-known Guo–Krasnoselskii and Avery–Henderson fixed-point theorems in a Banach ...
