A numerical scheme using multi-shockpeakons to compute solutions of the Degasperis-Procesi equation

We consider a numerical scheme for entropy weak solutions of the DP (Degasperis-Procesi) equation $u_t - u_{xxt} + 4uu_x = 3u_{x}u_{xx}+ uu_{xxx}$. Multi-shockpeakons, functions of the form $$ u(x,t) =sum_{i=1}^n(m_i(t) -hbox{sign}(x-x_i(t))s_i(t))e^{-|x-x_i(t)|}, $$ are solutions of the DP...
