The aim of this paper is to give construction and computation methods for generalized and unified representations of Stirling-type numbers and Bernoulli-type numbers and polynomials. Firstly, we define generalized and unified representations of the falling factorials. By using these new representations as components of the generating functions, we ...

The purpose of this article is to introduce a general shrinking projection algorithm for solving a finite family of quasi-variational inclusion problems in Hadamard manifolds. It is shown that under mild conditions, the sequence generated by the proposed algorithm converges strongly to a common solution to a finite family of quasi-variational inclu...

In many cases, the differential equations are converted into an equivalent functional equations involving integral operators generated by different kernels. The compactness property of the integral operators is often required for the existence of solutions for the corresponding differential equations. Our aim in this paper is to deal with Fréchet-K...

In this paper, non-perturbed and perturbed systems of non-linear differential equations with multiple constant delays are considered. Five new theorems on the qualitative properties of solutions, uniform asymptotic stability (UAS) and instability of trivial solution, boundedness and integrability of solutions, are obtained. The technique of the pro...

Introducing left invariant almost para-contact metric structures on Hom-Lie groups (Hom-Lie algebras), we study the normal and para-Sasakian conditions on them. The left-invariant curvature tensor properties of left-invariant para-Sasakian Hom-Lie groups are investigated. Some examples are commented as support of the obtained results.
