Positive solutions for the fractional Schrödinger equations with logarithmic and critical non‐linearities

open access: yesTransactions of the London Mathematical Society, Volume 8, Issue 1, Page 206-242, December 2021., 2021
Abstract In this paper, we study a class of fractional Schrödinger equations involving logarithmic and critical non‐linearities on an unbounded domain, and show that such an equation with positive or sign‐changing weight potentials admits at least one positive ground state solution and the associated energy is positive (or negative).

Existence and Regularity of a Weak Solution to a Class of Systems in a Multi-Connected Domain

open access: yesJournal of Partial Differential Equations, 2019
We consider the existence and regularity of a weak solution to a class of systems containing a p-curl system in a multi-connected domain. This paper extends the result of the regularity theory for a class containing a p-curl system that is given in the ...

Bäcklund transformations for several cases of a type of generalized KdV equation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 63, Page 3369-3377, 2004., 2004
An alternate generalized Korteweg‐de Vries system is studied here. A procedure for generating solutions is given. A theorem is presented, which is subsequently applied to this equation to obtain a type of Bäcklund transformation for several specific cases of the power of the derivative term appearing in the equation. In the process, several interesting,
