Existence of infinitely many solutions for the fractional Schr\"odinger- Maxwell equations

open access: yes, 2015
In this paper, by using variational methods and critical point theory, we shall mainly study the existence of infinitely many solutions for the following fractional Schr\"odinger-Maxwell equations $$( -\Delta )^{\alpha} u+V(x)u+\phi u=f(x,u), \hbox{in } \

Blow up of solutions to generalized Keller--Segel model [PDF]

open access: yesarXiv, 2008
The existence and nonexistence of global in time solutions is studied for a class of equations generalizing the chemotaxis model of Keller and Segel. These equations involve L\'evy diffusion operators and general potential type nonlinear terms.

Initial Blow-up of Solutions of Semilinear Parabolic Inequalities [PDF]

open access: yesarXiv, 2009
We obtain an upper bound on the initial blow-up of nonnegative solutions of second order semilinear parabolic inequalities when a superlinear exponent in the inequalities is not too large.
