Context-Free Fixed Points and Complete Classification of Orbits in Picard Iteration for Guarded Power Language Operators
Atanas Ilchev, Hristo Kiskinov, George Pashev +1
We study the language-theoretic structure of fixed points and finite Picard iterates for guarded q-power language operators. For the general operator, we prove that a context-free…
Why and How the Definition of the Conformable Derivative in the Lower Terminal Should be Changed
Hristo Kiskinov, Milena Petkova, Andrey Zahariev
This paper discusses some unusual consequences raised by the definition of the conformable derivative in the lower terminal. A replacement for this definition is proposed and state…
About Conformable Derivatives in Banach Spaces
Hristo Kiskinov, Milena Petkova, Andrey Zahariev +1
In the paper we discuss conformable derivative behavior in arbitrary Banach spaces and clear the connection between two conformable derivatives of different order. As a consequence…
Remarks about the existence of conformable derivatives and some consequences
Hristo Kiskinov, Milena Petkova, Andrey Zahariev
The aim of the present paper is to make some notes to the newly introduced conformable derivative as a type local fractional derivative and to present a surprising result about the…
