Finite-velocity diffusion on a comb
Trifce Sandev, Alexander Iomin
A Cattaneo equation for a comb structure is considered. We present a rigorous analysis of the obtained fractional diffusion equation, and corresponding solutions for the probabilit…
Shadow and Deflection Angle of Rotating Black Holes in Perfect Fluid Dark Matter with a Cosmological Constant
Sumarna Haroon, Mubasher Jamil, Kimet Jusufi +2
The presence of dark matter around a black hole remarkably affects its spacetime. We consider the effects of dark matter on the shadow of a new solution to the Einstein equations t…
Stationary dense operators in sequentially complete locally convex spaces
Marko Kostić, Stevan Pilipović, Daniel Velinov
The purpose of this paper is to investigate the stationary dense operators and their connection to distribution semigroups and abstract Cauchy problem in sequentially complete spac…
Vector-valued almost automorphic distributions and vector-valued almost automorphic ultradistributions
Marko Kosti\' c, Daniel Velinov
In this paper, we introduce the notions of a vector-valued almost automorphic distribution and a vector-valued almost automorphic ultradistribution, working in the framework of com…
A Note on Almost Anti-Periodic Functions in Banach Spaces
Marko Kostić, Daniel Velinov
The main aim of this note is to introduce the notion of an almost anti-periodic function in Banach space. We prove some characterizations for this class of functions, investigating…
Distinguishing rotating naked singularities from Kerr-like wormholes by their deflection angles of massive particles
Kimet Jusufi, Ayan Banerjee, Galin Gyulchev +1
We study the gravitational deflection of relativistic massive particles by Janis-Newman-Winicour (JNW) spacetimes (also known as a rotating source with a surface-like naked singula…
