Some existence and uniqueness results for a time-dependent coupled problem of the Navier-Stokes kind
(World Scientific, 1998)
In this paper, we consider some systems which are close to the instationary Navier-Stokes equations. The structure of these systems is the following: An (N +1)-dimensional equation for motion (including the incompressibility ...

Pullback attractor for a non-linear evolution equation in elasticity
(2014)
We prove the existence of a pullback attractor for a non{autonomous fourth order evolution equation arising in the fi eld of phase transitions and elasticity theory. The existence of several families of bounded absorbing ...

The sub-supertrajectory method. Application to the nonautonomous competition Lotka-Volterra model
(Sociedad Española de Matemática Aplicada, 2010)
In this paper we study in detail the pullback and forwards attractions to non-autonomous competition Lotka-Volterra system. In particular, under some conditions on the parameters, we prove the existence of a unique ...

Existence of invariant manifolds for coupled parabolic and hyperbolic stochastic partial differential equations
(2005)
An abstract system of coupled nonlinear parabolic-hyperbolic partial differential equations subjected to additive white noise is considered. The system models temperature dependent or heat generating wave phenomena in a ...

Stability results for neutral stochastic functional differential equations via fixed point methods
(Taylor and Francis, 2020)
In this paper we prove some results on the mean square asymptotic stability of a class of neutral stochastic differential systems with variable delays by using a contraction mapping principle. Namely, a necessary and ...

Analysis of a coupled fluid-structure model with applications to hemodynamics
(Society for Industrial and Applied Mathematics, 2016)
We propose and analyze a simplified fluid-structure coupled model for flows with compliant walls. As in [F. Nobile and C. Vergara, SIAM J. Sci. Comput., 30 (2008), pp. 731-763], the wall reaction to the fluid is modeled ...

An optimal control problem for a generalized Boussinesq model: The time dependent case
(Universidad Complutense de Madrid, 2007)
We consider an optimal control problem governed by a system of nonlinear partial differential equations modelling viscous incompressible flows submitted to variations of temperature. We use a generalized Boussinesq ...

Negatively Invariant Sets and Entire Trajectories of Set-Valued Dynamical Systems
(Springer Verlag (Germany), 2011)
Strongly negatively invariant compact sets of set-valued autonomous and nonautonomous dynamical systems on a complete metric space, the latter formulated in terms of processes, are shown to contain a weakly positively ...

On Optimal Pointwise in Time Error Bounds and Difference Quotients for the Proper Orthogonal
(SIAM, 2021-08-05)
In this paper, we resolve several long-standing issues dealing with optimal pointwisein time error bounds for proper orthogonal decomposition (POD) reduced order modeling of the heatequation. In particular, we study the ...
