On the Cauchy problem of dispersive Burgers type equations
- Mathematics
- 2021
We study the paralinearised weakly dispersive Burgers type equation: ∂tu+ ∂x[Tuu]− T ∂xu 2 u+ ∂x |D| α−1 u = 0, α ∈]1, 2[, which contains the main non linear ”worst interaction” terms, i.e low-high…
A Category of Banach Space Functors.
- Mathematics
- 2020
We consider the problem of normal forms from an abstract perspective. We introduce a functorial viewpoint on functional analysis, develop functional calculus and prove a general versal deformation…
Symplectic Manifolds and Isomonodromic Deformations.
- Mathematics
- 2020
We study moduli spaces of meromorphic connections (with arbitrary order poles) over Riemann surfaces together with the corresponding spaces of monodromy data (involving Stokes matrices). Natural…
Condições de transversalidades na mecânica
- Physics
- 2019
Neste trabalho nos mostramos a deducao da equacao de Euler-Lagrange e das condicoes de transversalidade em um contexto geometrico. Para isto, consideramos um funcional F, medindo algum aspecto fisico…
Exact controllability for quasilinear perturbations of KdV
- Mathematics
- 2017
We prove that the KdV equation on the circle remains exactly controllable in arbitrary time with localized control, for sufficiently small data, also in presence of quasi-linear perturbations, namely…
On geodesic completeness for Riemannian metrics on smooth probability densities
- Mathematics
- 2017
The geometric approach to optimal transport and information theory has triggered the interpretation of probability densities as an infinite-dimensional Riemannian manifold. The most studied…

On a certain type of nonlinear hyperbolic equations derived from astrophysical problems
- Mathematics, Physics
- 2016
Investigations of spherically symmetric motions of self-gravitating gaseous stars governed by the non-relativistic Newtonian gravitation theory or by the general relativistic theory lead us to a…
Rigidity of actions on presymplectic manifolds
- Mathematics
- 2016
We prove the rigidity of presymplectic actions of a compact semisimple Lie algebra on a presymplectic manifold of constant rank in the local and global case. The proof uses an abstract normal form…
On spherically symmetric solutions of the Einstein-Euler-de Sitter equations
- Mathematics, Physics
- 2015
We construct spherically symmetric solutions to the Einstein-Euler equations, which contains a positive cosmological constant, say, the EinsteinEuler-de Sitter equations. We assume a realistic…

A Free Boundary Optimization Problem
- Mathematics
- 1978
Given a convex set $Q \subset R^2 $ (bounded by a simple closed curve) and a constant $A > 0$, we determine the doubly-connected region $\Omega $ encircling (but not intersecting) Q, with area $|…
An implicit function theorem
- Mathematics
- 1978
Suppose thatF:D⊂Rn×Rm→Rn, withF(x0,y0)=0. The classical implicit function theorem requires thatF is differentiable with respect tox and moreover that ∂1F(x0,y0) is nonsingular. We strengthen this…
