Equivariant self-similar wave maps from Minkowski spacetime into 3-sphere

چکیده
We prove existence of a countable family of spherically symmetric self-similar wave maps from the Minkowski spacetime into the 3-sphere. These maps can be viewed as excitations of the ground state wave map found previously by Shatah. The first excitation is particularly interesting in the context of the Cauchy problem since it plays the role of a critical solution sitting at the threshold of singularity formation.

Dispersion and collapse of wave maps
We study numerically the Cauchy problem for equivariant wave maps from 3+1 Minkowski spacetime into the 3-sphere. On the basis of numerical evidence combined with stability analysis of self-similar solutions we formulate two conjectures. The first conjecture states that singularities which are produced in the evolution of sufficiently large initial data are approached in a universal manner give...
متن کاملFormation of singularities for equivariant 2+1 dimensional wave maps into the two-sphere
In this paper we report on numerical studies of the Cauchy problem for equivariant wave maps from 2+1 dimensional Minkowski spacetime into the two-sphere. Our results provide strong evidence for the conjecture that large energy initial data develop singularities in finite time and that singularity formation has the universal form of adiabatic shrinking of the degree-one harmonic map from R into S.

متن کاملOn Collapse of Wave Maps
We derive the universal collapse law of degree 1 equivariant wave maps (solutions of the sigma-model) from the 2+1 Minkowski spacetime, to the 2-sphere. To this end we introduce a nonlinear transformation from original variables to blowup ones. Our formal derivations are confirmed by numerical simulations.
متن کاملOn the existence of smooth self-similar blow-up profiles for the wave-map equation
Consider the equivariant wave map equation from Minkowski space to a rotationnally symmetric manifold N which has an equator (example: the sphere). In dimension 3, this article presents a necessary and sufficient condition on N for the existence of a smooth self-similar blow up profile. More generally, we study the relation between the minimizing properties of the equator map for the Dirichlet ...
