#### Controllability of fast diffusion coupled parabolic systems

(2014-12-31)

In this work we are concerned with the null controllability of coupled parabolic systems depending on a parameter and converging to a parabolic-elliptic system. We show the uniform null controllability of the family of ...

#### Estimating the division rate of the growth-fragmentation equation with a self-similar kernel

(2014-12-31)

We consider the growth-fragmentation equation and we address the problem of estimating the division rate from the stable size distribution of the population, which is easily measured, but non-smooth. We propose a method ...

#### Internal control for non-local Schrodinger and wave equations involving the fractional Laplace operator

(, 2014-12-31)

We analyse the interior controllability problem for a non-local Schr\"odinger equation involving the fractional Laplace operator $(-\Delta)^s$, $s\in(0,1)$, on a bounded $C^{1,1}$ domain $\Omega\subset\mathbb{R}^n$. The ...

#### Global exact controllability in infinite time of Schrodinger equation: multidimensional case

(2014-12-31)

In this paper, we study the problem of controllability of Schrödinger equation. We prove that the system is exactly controllable in infinite time to any po- sition. The proof is based on an inverse mapping theorem for ...

#### Derivation of a homogenized nonlinear plate theory from 3d elasticity

(2014-12-31)

We derive, via simultaneous homogenization and dimension reduction, the (Formula presented.)-limit for thin elastic plates whose energy density oscillates on a scale that is either comparable to, or much smaller than, the ...

#### On the existence and asymptotic stability of solutions for unsteady mixing-layer models

(2014-12-31)

We introduce in this paper some elements for the mathematical analysis of turbulence models for oceanic surface mixing layers. We consider Richardson-number based vertical eddy diffusion models. We prove the existence of ...

#### Finite time blow-up and condensation for the bosonic Nordheim equation

(2014-12-31)

The homogeneous bosonic Nordheim equation is a kinetic equation describing the dynamics of the distribution of particles in the space of moments for a homogeneous, weakly interacting, quantum gas of bosons. We show the ...

#### Robust null controllability for heat equations with unknown switching control mode

(2014-12-31)

We analyze the null controllability for heat equations in the presence of switching controls. The switching pattern is a priori unknown so that the control has to be designed in a robust manner, based only on the past ...

#### Generation of two-dimensional water waves by moving bottom disturbances

(2014-12-31)

In this study we investigate the potential and limitations of the wave genera- tion by disturbances moving at the bottom. More precisely, we assume that the wavemaker is composed of an underwater object of a given shape ...

#### A Hyperbolic system and the cost of the controllability for the Stokes system

(2014-12-31)

This paper is devoted to study the cost of the null controllability for the Stokes system. Using the control transmutation method, we show that the cost of driving the Stokes system to rest at time $T$ is of order $e^{CIT} ...
