in this paper, we find matrix representation of a class of sixth order sturm-liouville problem (slp) with separated, self-adjoint boundary conditions and we show that such slp have finite spectrum. also for a given matrix eigenvalue problem $hx=lambda vx$, where $h$ is a block tridiagonal matrix and $v$ is a block diagonal matrix, we find a sixth order boundary value problem of atkin...
Suppose G is a group of order p^2q^2 where p>q are prime numbers and suppose P and Q are Sylow p-subgroups and Sylow q-subgroups of G, respectively. In this paper, we show that up to isomorphism, there are four groups of order p^2q^2 when Q and P are cyclic, three groups when Q is a cyclic and P is an elementary ablian group, p^2+3p/2+7 groups when Q is an elementary ablian group an...
In this paper, a new smooth second order sliding mode control is proposed. This algorithm is a modified form of Super Twisting algorithm. The Super Twisting guarantees the asymptotic stability, but the finite time stability of proposed method is proved with introducing a new particular Lyapunov function. The Proposed algorithm which is able to control nonlinear systems with matched structured u...
Chaos synchronization of coupled fractional order differential equation is receiving increasing attention because of its potential applications in secure communications and control processing. The aim of this paper is synchronization between two identical or different delay fractional-order chaotic systems in finite time. At first, the predictor-corrector method is used to obtain the solutions ...
This article reports on a finite temperature phase transition in the four-dimensional X-cube model. The authors have proposed low spontaneously breaks 1-form subsystem symmetry.
