United Boundary-Domain Integro-Differential and Integral Equations to the Mixed BVP for a Compressible Stokes System with Variable Viscosity

Journal of Mathematics
The mixed BVP for a compressible Stokes system of PDEs with variable viscosity is considered in a bounded domain of three dimensions. Based on a specially constructed parametrix (Levi function), the problem is reduced to the united boundary-domain ...

A Study on Singular and Non-singular Elliptic and Parabolic PDEs

, 2021
The thesis is concerned about singular elliptic, parabolic partial differential equations (PDEs) and non-singular elliptic PDEs. A problem having nonlinearities that blow up to infinity near zero is considered as a ‘singular problem’.

Variational characterizations of weak solutions to the Dirichlet problem for mixed-type equations

, 2015
For linear and nonlinear second-order partial differential equations of mixed elliptic-hyperbolic type, we prove that weak solutions to the Dirichlet problem are characterized by a variational principle.

Finite element solution of crack-tip fields for an elastic porous solid with density-dependent material moduli and preferential stiffness

Advances in Mechanical Engineering
In this paper, the finite element solutions of crack-tip fields for an elastic porous solid with density-dependent material moduli are presented. Unlike the classical linearized case in which material parameters are globally constant under a small strain

On the dirichlet problem of mixed type for lower hybrid waves in axisymmetric cold plasmas [PDF]

, 2015
For a class of linear second order partial differential equations of mixed elliptic-hyperbolic type, which includes a well known model for analyzing possible heating in axisymmetric cold plasmas, we give results on the weak well-posedness of the ...
