The concepts of sigma-statistical convergence, statistical sigma-convergence and strong sigma(q)-convergence of single (ordinary) sequences have been introduced and studied in [M. Mursaleen, O. H. H. Edely, On the invariant ...

In the paper, we introduce the class of trigonometrically convex functions and using the Holder, Holder-Iscan, Power-mean and Improved power-mean integral inequality together with an identity we establish some new inequalities ...

In this paper, we establish the Fricke Group Gamma(F)(N) which is a new special group of Non-Euclidean Crystallograhic (NEC) group. We obtain this group whose congruence subgroup Gamma(0)(N) is expanded with Fricke reflection ...

This paper investigates a predator-prey model incorporating Allee effect and intraspecific competition with fading memory. In fact, the rate of past influence may have an essential role on the dynamics of both species since ...

Let Hc$$ {H}_c $$ be a (2n)x(2n)$$ (2n)\times (2n) $$ symmetric tridiagonal matrix with diagonal elements c is an element of Double-struck capital R$$ c\in \mathbb{R} $$ and off-diagonal elements one, and S$$ S $$ be a ...

This study is designed with the renewed concept of neutrosophic soft graph (briefly ns-graph) which is a combination of graphs and neutrosophic soft sets. We re-define notions of ns-graphs and ns-subgraphs with the different ...

Conformable fractional calculus is a relatively new branch of mathematics that seeks to extend traditional calculus to include non-integer order derivatives and integrals. This new form of calculus allows for a more precise ...

In the article, the parametric expressions of the dual ruled surfaces are expressed in terms of the vectorial moments of the Frenet vectors. The integral invariants of these surfaces are calculated. It is seen that the ...

In this article, we first introduce new Frenet formulas by making use of the properties of connected curves. Then applying these formulas we show that some decisive properties of Bertrand partner curve can be given in terms ...

In this study, in addition to classical Logistic and Gompertz models with three parameters, their growth models with four parameters were given. After that it is searched the effect of these growth models on the choice of ...
