主講內(nèi)容:
In this talk, we are concerned with wave solutions of a class of the KdV-Burgers-type systems by starting with Burgers-type equations, and then focus on the higher-order KdV-Burgers equation, a partial differential equation that occupies a prominent position in describing some physical processes in motion of turbulence and other unstable process systems. By means of the associated equivalence algebra, the Abel operator and the Lie symmetry, explicit-implicit wave solutions and asymptotic behaviors are presented.
