On power series solutions for the Euler equation, and the Behr-Nečas-Wu initial datum

In this work, we study the nonlinear spatially homogeneous Lan- dau equation with Maxwellian molecules, by using the spectral analysis, we show that the non linear Landau operators

The cauchy problem for radially symmetric homogeneous boltz- mann equation with shubin class initial datum and gelfand-shilov smoothing effect.4. THE CAUCHY PROBLEM FOR

We refer to [14] for the study of equation (1.1) or more general quasilinear parabolic equations with rough initial data, where we give new decay and uniqueness properties.. The

Our approach combines Arnold’s interpretation of the solution of Euler’s equation for incompressible and inviscid flu- ids as geodesics in the space of

Another class of stationary states are given by functions depending only on one variable (shear flows): for any smooth V (y) periodic in y, the couple ω(t, x, y) = V ′′ (y) and ψ(t,

We construct time quasi-periodic solutions of this equation made of lo- calized travelling profiles with compact support propagating over a stationary state depending on only

In this paper we present a geometric interpretation of the periodic Degasperis-Procesi equation as the geodesic flow of a right in- variant symmetric linear connection on

who endowed the universal Teichmüller space with a different complex Hilbert manifold structure in which the formula for the Weil–Petersson metric not only converges, but defines
