The Exponential Stability of Neutral Stochastic Delay Partial Differential Equations
(2007)
In this paper we analyse the almost sure exponential stability and ultimate boundedness of the solutions to a class of neutral stochastic semilinear partial delay differential equations. This kind of equations arises in ...

Asymptotic behavior of nonlinear systems in varying domains with boundary conditions on varying sets
(EDP Sciences, 2009)
For a fixed bounded open set Ω ⊂ RN , a sequence of open sets Ωn ⊂ Ω and a sequence of sets Γn ⊂ ∂Ω ∩ ∂Ωn, we study the asymptotic behavior of the solution of a nonlinear elliptic system posed on Ωn, satisfying Neumann ...

Stability for nematic liquid crystals with stretching terms
(World Scientific, 2010)
We study a nematic crystal model appearing in [Liu et al.,2007] modeling stretching effects depending on the different shape of microscopic molecules of the material, under periodic boundary conditions. The aim of the ...

Numerical null controllability of semi-linear 1-D heat equations: fixed point, least squares and Newton methods
(American Institute of Mathematical Sciences, 2012-09)
This paper deals with the numerical computation of distributed null controls for semilinear 1D heat equations, in the sublinear and slightly superlinear cases. Under sharp growth assumptions, the existence of controls has ...

Continuity of Lyapunov Functions and of Energy Level for a Generalized Gradient Semigroup
(2012)
The global attractor of a gradient-like semigroup has a Morse decomposition. Associated to this Morse decomposition there is a Lyapunov function (di erentiable along solutions)-de ned on the whole phase space- which proves ...

h-stability in p-th moment of neutral pantograph stochastic di erential equations with Markovian switching driven by L evy noise
(Elsevier, 2021-10-01)
In this paper we investigate the h-stability in p-th moment of neutral pantograph stochastic differential equations with Markovian switching driven by Lévy noise. The main tool used to prove the results is the Lyapunov ...

Local strong solution for the incompressible Korteweg model
(Elsevier, 2006-02)
We consider a Navier-Stokes type system with a Korteweg stress tensor, coupled with a concentration equation without diffusion. We give a result concerning the local in time existence (and uniqueness) of strong solution ...

On a nonlinear volterra integrodifferential equation involving fractional derivative with Mittag-Leffler Kernel
(American Mathematical Society, 2021-08-01)
In this paper, a nonlinear time-fractional Volterra equation with nonsingular Mittag-Leffler kernel in Hilbert spaces is studied. By applying the properties of Mittag-Leffler functions and the method of eigenvalue expansion, ...

Adaptación a los nuevos Grados de las metodologías docentes empleadas en una asignatura de Estadística Económico-Empresarial
(Universidad Pablo de Olavide, 2012)
Durante el presente curso 2009/2010 la Universidad Pablo de Olavide (UPO), de Sevilla, ha puesto en marcha el nuevo mapa de titulaciones adaptado al Espacio Europeo de Educación Superior (EEES), el cual está compuesto por ...

On the uniqueness and regularity of the Primitive Equations imposing additional anisotropic regularity
(Elsevier, 2005-07)
In this note, we prove that given u a weak solution of the Primitive Equations, imposing an additional condition on the vertical derivative of the velocity u (concretely ∂zu ∈ L∞(0, T;L2(Ω)) ∩ L2(0, T; H1(Ω))), then two ...
