Evaluation of integrals and series with uncommon methods
Volume 5, Issue 2 , July 2023, , Pages 29-38
Abstract
Definite integrals and series are calculated using uncommon methods: Feynman's parametrization, Schwinger's representation, and Cauchy's complex integration for series. Read More
On some new observations on Kurepa's left factorial
Volume 4, Issue 3 , June 2022, , Pages 1-8
Abstract
After a brief historical excursus, we prove in a simple way some properties of Kurepa's function, the left factorial. We introduce Kurepa's hypothesis, propose a new description, ... Read More
Some critical remarks of recent results on F-contractions in b-metric spaces
Volume 4, Issue 2 , April 2022, , Pages 1-10
Abstract
In this paper, we analyze, generalize and correct some recent results on F-contractions within b-metric spaces. In all results, our only assumption is the strict growth of the function ... Read More
On various types of compatible Jungck--Rhoades pairs of mappings in C*-algebra valued metric spaces
Volume 3, Issue 3 , September 2021, , Pages 1-25
Abstract
In this paper, among other things, we have established four different types of compatible mappings that work in the context of C*-algebra valued metric spaces. The obtained ... Read More
