L~1-convergence rate of relaxation approximations to conservation laws with boundary

LI Xiao-meng1,CUI Hui-ping2,LIU Hong-xia1(1.Department of Mathematics,Jinan University,Guangzhou 510632,China;2.Guangdong Pharmaceutical University;Guangzhou 510006,China)  
L1-convergence rate of solutions to a stiff relaxation system with initial-boundary value condition to its equilibrium solutions is studied.Assume that the boundary data is a nontransonic state and initial data is a small perturbation,by using matching method and the traveling wave solutions,the error between the relaxation approximations and its equilibrium solution is estimated to be bounded by O(εlnε+ε) in L1-norm,if the equilibrium solutions are piecewise smooth with finitely many discontinuities for the initial-boundary value problem of the stiff relaxation system.
