Some A priori estimates for the homogeneous Landau equation with soft potentials
Radjesvarane Alexandre, Jie Liao, Chunjin Lin
This paper deals with the derivation of some á priori estimates for the homogeneous Landau equation with soft potentials. Using the coercivity of the Landau operator for soft poten…
Well-posedness of The Prandtl Equation in Sobolev Spaces
Radjesvarane Alexandre, Ya-Guang Wang, Chao-Jiang Xu +1
We develop a new approach to study the well-posedness theory of the Prandtl equation in Sobolev spaces by using a direct energy method under a monotonicity condition on the tangent…
Landau linearized operator and hypoellipticity
Radjesvarane Alexandre
We consider the linearized Landau operator for which we provide simple proofs of hypoellipticity, and in particular we recover the recent results of H\' erau and Pravda-Starov \cit…
A Gaussian beam approach for computing Wigner measures in convex domains
Jean-Luc Akian, Radjesvarane Alexandre, Salma Bougacha
A Gaussian beam method is presented for the analysis of the energy of the high frequency solution to the mixed problem of the scalar wave equation in an open and convex subset, wit…
Fractional order kinetic equations and hypoellipticity
Radjesvarane Alexandre
We give simple proofs of hypoelliptic estimates for some models of kinetic equations with a fractional order diffusion part. The proofs are based on energy estimates together with…
The Boltzmann equation without angular cutoff in the whole space: III, Qualitative properties of solutions
Radjesvarane Alexandre, Yoshinori Morimoto, Seiji Ukai +2
This is a continuation of our series of works for the inhomogeneous Boltzmann equation. We study qualitative properties of classical solutions, precisely, the full regularization i…
Global existence and full regularity of the Boltzmann equation without angular cutoff
Radjesvarane Alexandre, Y. Morimoto, Seiji Ukai +2
We prove the global existence and uniqueness of classical solutions around an equilibrium to the Boltzmann equation without angular cutoff in some Sobolev spaces. In addition, the…
Regularizing effect and local existence for non-cutoff Boltzmann equation
Radjesvarane Alexandre, Y. Morimoto, Seiji Ukai +2
The Boltzmann equation without Grad's angular cutoff assumption is believed to have regularizing effect on the solution because of the non-integrable angular singularity of the cro…
