Abstract

We continue our study of the collision of two solitons for the subcritical generalized KdV equations. In a previous paper, mainly devoted to the case of the quartic gKdV equation, we have introduced a new framework to understand the collision of two solitons in the case where one soliton is small with respect to the other. In this paper, we consider the case of a general nonlinearity $f(u)$ for which the two solitons are nonlinearly stable. We prove that in this situation the two solitons survive and we describe the collision at the main orders.

Boundary Regularity for Fully Nonlinear Degenerate Elliptic Equations

This paper investigates fully nonlinear degenerate elliptic equations of the form $|Du|^γF(D^2u) = f$ with $γ>0$ {and $F(0)=0$}. Using a unified compactness and perturbation framework, we {establish} $C^1$ regularity on $C^{1,\mathrm{Dini}}$ domains and {$C^{1,α_0}$ regularity on $C^{1,α}$ domains}, {where $α_0=\min\{α,1/(1+γ)\}$}. {In addition}, we construct a counterexample to show that {$W^{2,δ}$ regularity does not hold for any $δ>0$}.

Localizing acoustic and electromagnetic waves in space and time

We study time-dependent acoustic and electromagnetic waves governed by the scalar wave equation or Maxwell's equations in a bounded three-dimensional domain. We establish the existence of time-dependent boundary excitations that can be prescribed on any open subset of the boundary of the domain such that the associated waves are strongly localized in space in the sense that they possess arbitrarily large norms in a given subdomain and on a given time-interval, while remaining arbitrarily small in any other given subdomain for all times. Similarly, we also show the existence of boundary data such that the associated waves are strongly localized in time in the sense that they possess arbitrarily large norms in a given subdomain and on a given time-interval, while remaining arbitrarily small on the same subdomain but on any other prescribed time-interval. In case that we have access to the possibly inhomogeneous coefficients in the wave equation or in the Maxwell system, we also give explicit constructions to obtain boundary data that generate these localized waves, and we comment on possible applications.

Brunn-Minkowski Inequality for p-Harmonic Measures

We prove a Brunn--Minkowski inequality for a functional associated with p-harmonic measures for $1<p<n+1$, on a class of convex domains satisfying suitable conditions. Under an additional first-variation assumption, we also prove uniqueness up to dilation about the origin for the corresponding Minkowski problem. We also study geometric conditions involving level sets, support functions, and Gaussian curvature for the problem with a fixed inner body.
