In this paper, we establish the solvability of martingale solutions for the stochastic NavierStokes equations with ItôLévy noise in bounded and unbounded domains in $ \mathbb{R} ^d$,$d=2,3.$ The tightness criteria for the laws of a sequence of semimartingales is obtained from a theorem of Rebolledo as formulated by Metivier for the Lusin space valued processes. The existence of martingale solutions (in the sense of Stroock and Varadhan) relies on a generalization of MintyBrowder technique to stochastic case obtained from the local monotonicity of the drift term.

In this work we study the exponential stabilization of the two and threedimensional
NavierStokes equations in a bounded domain $\Omega$, around a given steadystate flow,
by means of a boundary control. In order to determine a feedback law, we consider an
extended system coupling the NavierStokes equations with an equation satisfied by the
control on the domain boundary. While most traditional approaches apply a feedback
controller via an algebraic Riccati equation, the StokesOseen operator or
extension operators, a Galerkin method is proposed instead in this study.
The Galerkin method permits to construct a stabilizing boundary control
and by using energy a priori estimation technics, the exponential decay is obtained.
A compactness result then allows us to pass to the limit in the system satisfied by
the approximated solutions. The resulting feedback control is proven to be globally
exponentially stabilizing the steady states of the two and threedimensional
NavierStokes equations.

Boundary approximate controllability of some linear parabolic systems

This paper focuses on the boundary approximate controllability of two classes of linear parabolic systems, namely a system of $n$ heat equations coupled through constant terms and a $2 \times 2$ cascade system coupled by means of a first order partial differential operator with spacedependent coefficients.
For each system we prove a sufficient condition in any space dimension and we show that this condition turns out to be also necessary in one dimension with only one control.
For the system of coupled heat equations we also study the problem on rectangle, and we give characterizations depending on the position of the control domain.
Finally, we prove the distributed approximate controllability in any space dimension of a cascade system coupled by a constant first order term.
The method relies on a general characterization due to H.O. Fattorini.

We present an analysis of regularity and stability of solutions corresponding to wave equation with dynamic boundary conditions. It has been known since the pioneering work by [26, 27, 30] that addition of dynamics to the boundary may change drastically both regularity and stability properties of the underlying system.
We shall investigate these properties in the context of wave equation with the damping affecting either the interior dynamics or the boundary dynamics or both.
This leads to a consideration of a wave equation acting on a bounded 3d domain coupled with another second order dynamics acting on the boundary. The wave equation is equipped with a viscoelastic damping, zero Dirichlet boundary conditions on a portion of the boundary and dynamic boundary conditions. These are general Wentzell type of boundary conditions which describe wave equation oscillating on a tangent manifold of a lower dimension.
We shall examine regularity and stability properties of the resulting system as a function of strength and location of the dissipation. Properties such as wellposedness of finite energy solutions, analyticity of the associated semigroup,
strong and uniform stability will be discussed.
The results obtained analytically are illustrated by numerical analysis. The latter shows the impact of various
types of dissipation on the spectrum of the generator as well as the dynamic behavior of the solution on a rectangular domain.

In this paper, we give an existence result for the following dynamical equilibrium problem:
$\langle \frac{du}{dt},vu(t)\rangle+F(u(t),v)\geq 0 \;\; \forall v\in K $ and for $a.e. \;t \geq 0$, where $K$ is a closed convex set in a Hilbert space and $ F:K \times K \rightarrow \mathbb{R}$ is a monotone bifunction. We introduce a class of demipositive bifunctions and use it to study the asymptotic behaviour of
the solution $ u(t) $ when $ t\rightarrow\infty $. We obtain weak convergence of $ u(t) $ to some solution $x\in K$ of the equilibrium problem $F(x,y)\geq 0 $ for every $y\in K$. Our applications deal with the asymptotic behaviour of the dynamical convex minimization and dynamical system associated to saddle convexconcave bifunctions. We then present a new neural model for solving a convex programming problem.

In this paper, we investigate the existence and uniqueness of solutions for a class
of evolutionary integral equations perturbed by a noise arising in the theory of heat conduction. As a motivation of our results, we study an optimal
control problem when the control enters the system together with the noise.

In this paper, we study LandauLifshitz equations of ferromagnetism with a total energy that does not include a socalled exchange energy. Many problems, including existence, stability, regularity and asymptotic behaviors, have been extensively studied for such equations of models with the exchange energy. The problems turn out quite different and challenging for LandauLifshitz equations of noexchange energy models because the usual methods based on certain compactness do not apply. We present a new method for the existence of global weak solution to the LandauLifshitz equation of noexchange energy models based on the existence of regular solutions for smooth data and certain stability of the solutions.
We also study higher time regularity, energy identity and asymptotic behaviors in some special cases for weak solutions.

Control of blowup singularities for nonlinear wave equations

While the global boundary control of nonlinear wave equations that
exhibit blowup is generally impossible, we show on a typical
example, motivated by laser breakdown, that it is possible to
control solutions with small data so that they blow up on a
prescribed compact set bounded away from the boundary of the
domain. This is achieved using the representation of singular
solutions with prescribed blowup surface given by Fuchsian
reduction. We outline on this example simple methods that may be
of wider applicability.

We extend the method of exact boundary controllability of strictly hyperbolic equations developed by W. Littman [22,23] to a large class of hyperbolic systems with constant coefficients. Our approach is based on the knowledge of the singularities of the fundamental solution of hyperbolic operators.

We consider a coupled parabolichyperbolic PDE system arising in fluidstructure interaction, where the coupling is exercised at the interface between the two media. This paper is a study in contrast on stability properties of the overall coupled system under two scenarios: the case with interior dissipation of the structure, and the case without. In the first case, uniform stabilization is achieved (by a $\lambda$domain analysis) without geometrical conditions on the structure, but only on an explicitly identified space $Ĥ$ of codimension one with respect to the original energy state space $H$ where semigroup wellposedness holds. In the second case, only rational (a fortiori strong) stability is possible, again only on the space $Ĥ$, however, under geometrical conditions of the structure, which e.g., exclude a sphere. Many classes of good geometries are identified. Recent papers [6,9] show uniform stabilization on all of $H$, and without geometrical conditions; however, with dissipation at the boundary interface.
