Dispersion for the Schrödinger equation inside strictly convex domains: the general case

Oana Ivanovici, Fabrice Planchon

We consider a general smooth bounded strictly convex domain of dimension and describe dispersion for the semiclassical Schrödinger equation with Dir…

Dispersion for the wave equation with Neumann boundary condition inside general strictly convex domains

Oana Ivanovici, Diego Sanchez Sanz

We consider the wave equation on a manifold of dimension d>1 with smooth strictly convex boundary, with Neumann boundary condition. We construct a sharp local in time parametrix fo…

Strichartz and dispersive estimates for quantum bouncing ball model: exponential sums and Van der Corput methods in 1d semi-classical Schrödinger equations

Oana Ivanovici

We analyze the one-dimensional semi-classical Schrödinger equation on the half-line with a linear potential and Dirichlet boundary conditions. Our main focus is on establishing imp…

Dispersive estimates for the wave and the Klein-Gordon equations in large time inside the Friedlander domain

Oana Ivanovici

We prove global in time dispersion for the wave and the Klein-Gordon equation inside the Friedlander domain by taking full advantage of the space-time localization of caustics and…

Potential energy surfaces without unphysical discontinuities: the Coulomb-hole plus screened exchange approach

J. Arjan Berger, Pierre-François Loos, Pina Romaniello

In this work we show the advantages of using the Coulomb-hole plus screened-exchange (COHSEX) approach in the calculation of potential energy surfaces. In particular, we demonstrat…

Strichartz estimates for the wave equation on a 2d model convex domain

Oana Ivanovici, Gilles Lebeau, Fabrice Planchon

We prove better Strichartz type estimates than expected from the (optimal) dispersion we obtained in our earlier work on a 2d convex model. This follows from taking full advantage…

Dispersion for the wave equation outside a ball and counterexamples

Oana Ivanovici, Gilles Lebeau

The purpose of this note is to prove dispersive estimates for the wave equation outside a ball in R^d. If d = 3, we show that the linear flow satisfies the dispersive estimates as…

Are Maxwell's equations Lorentz-covariant?

D V Redzic

The statement that Maxwell's electrodynamics in vacuum is already covariant under Lorentz transformations is commonplace in the literature. We analyse the actual meaning of that st…

Dispersion for the wave equation inside strictly convex domains I: the Friedlander model case

Oana Ivanovici, Gilles Lebeau, Fabrice Planchon

We consider a model case for a strictly convex domain of dimension with smooth boundary and we describe dispersion for the wave equation with Dirichlet boundary condition…

Counter-examples to the Strichartz estimates for the wave equation in domains II

Oana Ivanovici

We consider a smooth and bounded domain of dimension d>1 and we construct solutions to the wave equation with Dirichlet boundary conditions which contradict the Strichartz estimate…

Square function and heat flow estimates on domains

Oana Ivanovici, Fabrice Planchon

The first purpose of this note is to provide a proof of the usual square function estimate on Lp (?). It turns out to follow directly from a generic Mikhlin multiplier theorem obta…
