EECT is primarily devoted to papers on analysis and control of infinite dimensional systems with emphasis on applications to PDE's and FDEs. Topics include:
* Modeling of physical systems as infinitedimensional processes
* Direct problems such as existence, regularity and wellposedness
* Stability, longtime behavior and associated dynamical attractors
* Indirect problems such as exact controllability, reachability theory and inverse problems
* Optimization  including shape optimization  optimal control, game theory and calculus of variations
* Wellposedness, stability and control of coupled systems with an interface. Free boundary problems and problems with moving interface(s)
* Applications of the theory to physics, chemistry, engineering, economics, medicine and biology
The journal also welcomes excellent contributions on interesting and challenging ODE systems which arise as simplified models of infinitedimensional structures.

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.

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 the null controllability of weakly degenerate
parabolic systems with two different diffusion coefficients and one control force.
To obtain this aim, we had to develop new global Carleman estimates for a
degenerate parabolic equation, with weight functions different from the ones of [2],
[10] and [31].

A gradientlike property is established for second order semilinear conservative systems in presence of a linear damping term which is asymptotically weak for large times. The result is obtained under the condition that the only critical points of the potential are absolute minima. The damping term may vanish on large intervals for arbitrarily large times and tends to $0$ at infinity, but not too fast (in a nonintegrable way). When the potential satisfies an adapted, uniform, Łojasiewicz gradient inequality, convergence to equilibrium of all bounded solutions is shown, with examples in both analytic and nonanalytic cases.

We analyse the longterm properties of a $C_0$semigroup describing
the solutions to a nonlinear thermoelastic diffusion plate,
recently derived by Aouadi [1], where the heat and diffusion flux
depends on the past history of the temperature and the chemical
potential gradients through memory kernels. First we prove the
wellposedness of the initialboundaryvalue problem using the
$C_0$semigroup theory of linear operators. Then we show, without
rotational inertia, that the thermal and chemical potential coupling
is strong enough to guarantee the quasistability. By showing that
the system is gradient and asymptotically compact, the existence of
a global attractor whose fractal dimension is finite is proved.

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.

In this paper, we consider the Cauchy problem of a sixth order CahnHilliard equation with the inertial term,
\begin{eqnarray*}
ku_{t t} + u_t  \Delta^3 u  \Delta(a(u) \Delta u \frac{a'(u)}2\nabla u^2 + f(u))=0.
\end{eqnarray*}
Based on Green's function method together with energy estimates, we get the global existence and
optimal decay rate of solutions.

We investigate the initial value problems for some semilinear wave, heat and Schrödinger equations in two space dimensions, with exponential nonlinearities. Using the potential well method based on the concepts of invariant sets, we prove either global wellposedness or finite time blowup.
