  • Long-time behavior of solutions to a quasilinear parabolic equationLong-time behavior of solutions to a quasilinear parabolic equation

    Abstract: In this paper, we study the first initial boundary value problem for a class of quasilinear degenerate parabolic equations involving weighted p-Laplacian operators. The existence and uniqueness of a weak solution with respect to initial values is ensured by an application of the Faedo - Galerkin approximation and compact method. Moreov...

    Abstract: Synchronization is a ubiquitous feature in many natural systems and nonlinear science. In this paper, the synchronization in complete network consisting of n nodes is studied. Each node is connected to all other nodes by linear coupling and it is represented by a system of ordinary differential equations of FitzHugh-Nagumo type which i...

  • Novel exponential stability criterion of nonlinear systems with interval time-varying delaysNovel exponential stability criterion of nonlinear systems with interval time-varying delays

    Abstract: This paper presents a new result on delay-dependent exponential stability for nonlinear linear systems with interval time-varying delay. By constructing a set of improved Lyapunov-Krasovskii functionals combined with Wirtinger-based integral inequality, a new delay-dependent condition is established in terms of linear matrix inequality...

    Abstract: Viet Nam is a tropical country with monsoons, which is suitable for growing different kinds of flowers including Oncidium-sweet sugar Orchids. Production of Orchids in Viet Nam has not fully developed, compared with the potentials of this kind of flowers due to a lack of appropriate process of technology to produce Orchids. Research on...
