A Whitney extension theorem for functions taking values in scales of Banach spaces

Pietro Baldi

We introduce a modified version of the Whitney extension operators for collections of functions from a closed subset of $R^{n}$ into scales of Banach spaces with smoothing o…

Longer lifespan for many solutions of the Kirchhoff equation

Pietro Baldi, Emanuele Haus

We consider the Kirchhoff equation $\partial_{tt} u - Δ u (1 + \int_{T^{d}} ∣\nabla u ∣^{2}) = 0$ on the $d$ -dimensional torus $T^{d}$ , and its Cauchy problem…

On the normal form of the Kirchhoff equation

Pietro Baldi, Emanuele Haus

Consider the Kirchhoff equation $\partial_{tt} u - Δ u (1 + \int_{T^{d}} ∣\nabla u ∣^{2}) = 0$ on the $d$ -dimensional torus $T^{d}$ . In a previous paper we…

Quasi-periodic incompressible Euler flows in 3D

Pietro Baldi, Riccardo Montalto

We prove the existence of time-quasi-periodic solutions of the incompressible Euler equation on the three-dimensional torus $\T^3$, with a small time-quasi-periodic external force.…
