(Applied Mathematical Modelling, 2023)
This paper considers control systems with impulses that are saturated and asymmetrically saturated which are used to examine the synchronization of inertial neural networks (INNs) with time-varying delay and coupling delays. ...

This project presents that using a modified version of Skip-gram with negative sampling
with weight tying proposed by Assylbekov and Takhanov (2019) word embedding of each
word can be decomposed into two subvectors: x ...

(Advances in Difference Equations, 2020)
It is known that all solutions of the difference equation
Δx(n)+p(n)x(n−k)=0,n≥0,
where {p(n)}∞n=0 is a nonnegative sequence of reals and k is a natural number, oscillate if lim infn→∞∑n−1i=n−kp(i)>(kk+1)k+1. In the ...

The theory of option pricing made a dramatic step forward when Black and Scholes
published a centennial paper with a solution for the prices of European call and put
options. However, their solution only deals with the ...

his paper describes the soliton surfaces approach to the Witten-Dijkgraaf-E.Verlinde-H. Verlinde (WDVV) equation. We constructed the surface associated with the WDVV equations using Sym-Tafel formula, which gives a connection ...

We consider fuzzy shunting inhibitory cellular neural networks (FSICNNs) with time-varying coefficients and constant delays. By virtue of continuation theorem of coincidence degree theory and Cauchy–Schwartz inequality, ...

(arxiv, 2020)
We investigate the local and global dynamics of two 1-Dimensional (1D) Hamiltonian lattices
whose inter-particle forces are derived from non-analytic potentials. In particular, we study the
dynamics of a model governed ...

In this paper we present L2
and Lp
versions of the geometric Hardy inequalities in
half-spaces and convex domains on stratifed (Lie) groups. As a consequence, we
obtain the geometric uncertainty principles. We give ...

We present some variants of Burgers-type equations for incompressible and isothermal planar flow of viscous non-Newtonian fluids based on the Cross, the Carreau and the power-law rheology models, and on a symmetry assumption ...

One of the important problem of the theory of polynomial identi tites in algebra is describe all varieties of algebras with given system of
identities. Our aim is to classify all subvarieties of the variety of bicom ...
