Sampling-Based Event-Triggered Control for Neutral-Type Complex-Valued Neural Networks with Partly Unknown Markov Jump and Time-Varying Delay

open access: yesComplexity, 2021
This work is devoted to studying the stochastic stabilization of a class of neutral-type complex-valued neural networks (CVNNs) with partly unknown Markov jump.

Inequalities and bounds for the eigenvalues of the sub-Laplacian on a strictly pseudoconvex CR manifold [PDF]

open access: yes, 2012
We establish inequalities for the eigenvalues of the sub-Laplace operator associated with a pseudo-Hermitian structure on a strictly pseudoconvex CR manifold.

Some inequalities for maximum modules of polynomials

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1991
A well-known result of Ankeney and Rivlin states that if p(z) is a polynomial of degree n, such that p(z)≠0 in |z|

Robust stability analysis of impulsive complex-valued neural networks with time delays and parameter uncertainties

open access: yesJournal of Inequalities and Applications, 2017
The present study considers the robust stability for impulsive complex-valued neural networks (CVNNs) with discrete time delays. By applying the homeomorphic mapping theorem and some inequalities in a complex domain, some sufficient conditions are ...

A domain of influence in the Moore–Gibson–Thompson theory of dipolar bodies

open access: yesJournal of Taibah University for Science, 2020
We establish a domain of influence theorem for the mixed initial-boundary value problem in the context of the Moore–Gibson–Thompson theory of thermoelasticity for dipolar bodies. Based on the data of the mixed problem, we define, for a finite time t>0, a

Bubble effect on Kelvin-Helmholtz' instability [PDF]

open access: yes, 2004
We derive boundary conditions at interfaces (contact discontinuities) for a class of Lagrangian models describing, in particular, bubbly flows. We use these conditions to study Kelvin-Helmholtz' instability which develops in the flow of two superposed ...

The Kato Square Root Problem for Mixed Boundary Conditions [PDF]

open access: yes, 2013
We consider the negative Laplacian subject to mixed boundary conditions on a bounded domain. We prove under very general geometric assumptions that slightly above the critical exponent $\frac{1}{2}$ its fractional power domains still coincide with ...

A Class of Symmetric Fractional Differential Operator Formed by Special Functions

open access: yesJournal of Mathematics, 2022
In light of a certain sort of fractional calculus, a generalized symmetric fractional differential operator based on Raina’s function is built. The generalized operator is then used to create a formula for analytic functions of type normalized.

Estimates of the gaps between consecutive eigenvalues of Laplacian [PDF]

open access: yes, 2013
By the calculation of the gap of the consecutive eigenvalues of $\Bbb S^n$ with standard metric, using the Weyl's asymptotic formula, we know the order of the upper bound of this gap is $k^{\frac{1}{n}}.$ We conjecture that this order is also right for ...

Existence of holomorphic sections and perturbation of positive line bundles over $q$--concave manifolds

open access: yes, 2004
By using asymptotic Morse inequalities we give a lower bound for the space of holomorphic sections of high tensor powers in a positive line bundle over a q-concave domain.
