Existence of Weak Solutions to Nonlocal PDEs With a Generalized Definition of Caputo Derivative [PDF]

open access: closedMediterranean Journal of Mathematics, 2023
Some compactness criteria that are analogies of the Aubin–Lions lemma for the existence of weak solutions of nonlinear evolutionary PDEs play crucial roles for the existence of weak solutions to time-fractional PDEs. Based on this fact, in this paper, we consider the existence of weak solutions to a kind of partial differential equations with Caputo ...

Classic Solutions of Boundary Value Problems for Partial Differential Equations with Operator of Finite Index in the Main Part of Equation

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2019
This paper is an attempt to give the review of a part of our results in the area of singular partial differential equations. Using the results of the theory of complete generalized Jordan sets we consider the reduction of the PDE with the irreversible ...

On a Level-Set Method for Ill-Posed Problems with Piecewise Nonconstant Coefficients

open access: yesJournal of Applied Mathematics, 2013
We investigate a level-set-type method for solving ill-posed problems, with the assumption that the solutions are piecewise, but not necessarily constant functions with unknown level sets and unknown level values.

Can there be a general nonlinear PDE theory for the existence of solutions ?

open access: yes, 2004
Contrary to widespread perception, there is ever since 1994 a unified, general type independent theory for the existence of solutions for very large classes of nonlinear systems of PDEs. This solution method is based on the Dedekind order completion of suitable spaces of piece-wise smooth functions on the Euclidean domains of definition of the ...
