The Semigroup generated by a Temple Class System with Large Data

Abstract: We consider the Cauchy problem $$u_t + [F(u)]_x=0, u(0,x)=\bar u(x) (*)$$ for a nonlinear $n\times n$ system of conservation laws with coinciding shock and rarefaction curves. Assuming the existence of a coordinates system made of Riemann invariants, we prove the existence of a weak solution of (*) that depends in a lipschitz continuous way on the initial data, in the class of functions with arbitrarily large but bounded total variation.
