Convergence of solutions to nonlinear dispersive equations without convexity conditions

Abstract

This paper gets a series of results about the convergence of solutions {u_δ ^c} for partial differential equations of the form u_t + f_x(u) + δu_χχχ ≡ εu_χχ and u_t + f_χ(u) + δu_χχχ ≡ εu_χχ as ε and δ approach zero. Where the flux functions need no convexity conditions

Keywords:

• Nonlinear dispersive
• convexity condition
