Abstract:
This article studies the characteristic Cauchy
problem for the Yang-Mills-Vlasov (YMV) system in temporal gauge,
where the initial data are specified on two intersecting
smooth characteristic hypersurfaces of Minkowski spacetime
.
Under a
hypothesis on the data,
we solve the initial constraint problem and the evolution problem.
Local in time existence and uniqueness results are established
thanks to a suitable combination of the method of characteristics,
Leray's Theory of hyperbolic systems and techniques
developed by Choquet-Bruhat for ordinary spatial Cauchy
problems related to (YMV) systems.
