Surfaces of Constant Curvature in the Pseudo-Galilean Space

International Journal of Mathematics and Mathematical Sciences, 2012
We develop the local theory of surfaces immersed in the pseudo-Galilean space, a special type of Cayley-Klein spaces. We define principal, Gaussian, and mean curvatures.

Evolution equations in generalized Stepanov-like pseudo almost automorphic spaces

Electronic Journal of Differential Equations, 2012
In this article, first we introduce and study the concept of $mathbb{S}_{gamma}^p$-pseudo almost automorphy (or generalized Stepanov-like pseudo almost automorphy), which is more general than the notion of Stepanov-like pseudo almost automorphy due ...

The Vlasov equation with strong magnetic field and oscillating electric field as a model for isotop resonant separation

Electronic Journal of Differential Equations, 2002
We study the qualitative behavior of solutions to the Vlasov equation with strong external magnetic field and oscillating electric field. This model is relevant to the understanding of isotop resonant separation.

Pseudo-differential operators and equations in a discrete half-space

Mathematical Modelling and Analysis, 2018
We introduce a digital pseudo-differential operator acting in discrete Sobolev--Slobodetskii spaces and consider pseudo-differential equations with such operators in a discrete half-space.

Weighted pseudo almost automorphic solutions to functional differential equations with infinite delay

Electronic Journal of Differential Equations, 2016
In this article, we first establish some results on composition of Stepanov-like weighted pseudo almost automorphic functions so called class r and class infinity under a uniform continuity condition with respect to L^p-norm.
