Metrical almost periodicity: Levitan and Bebutov concepts
B. Chaouchi, M. Kostić, D. Velinov
In this paper, we analyze Levitan and Bebutov metrical approximations of functions by trigonometric polynomials and -periodic type functions, where…
Metrical approximations of functions
B. Chaouchi, M. Kostic, D. Velinov
In this paper, we analyze metrical approximations of functions by trigonometric polynomials and -periodic type functions, where $\emptyset \neq Λ\sub…
-Periodic solutions of abstract integro-differential impulsive equations on Banach space
Michal Fečkan, Marko Kostić, Daniel Velinov
In this paper, we investigate the existence and uniqueness of -periodic solutions for a class of the abstract impulsive integro-differential equations on Banach space.
-Almost periodic type functions and applications
M. T. Khalladi, M. Kostić, M. Pinto +2
In this paper, we introduce several various classes of -almost periodic type functions and their Stepanov generalizations, where and We also consider…
Semi-Bloch periodic functions, semi-anti-periodic functions and applications
Belkacem Chaouchi, Marko Kostić, Stevan Pilipović +1
In this paper, we introduce the notions of semi-Bloch periodic functions and semi-anti-periodic functions. Stepanov semi-Bloch periodic functions and Stepanov semi-anti-periodic fu…
Recurrent strongly continuous operator families on Banach space
Chung-Chuan Chen, Marko Kostić, Daniel Velinov
In this paper, we analyze recurrent -semigroups of bounded operators on Banach spaces. We also introduce the notion of a (uniformly) -rigid semigroups of bounded oper…
