Rosenau–Hyman equation

From Wikipedia, the free encyclopedia

The Rosenau–Hyman equation or K(n,n) equation is a KdV-like equation having compacton solutions. This nonlinear partial differential equation is of the form[1]

The equation is named after Philip Rosenau and James M. Hyman, who used in their 1993 study of compactons.[2]

The K(n,n) equation has the following traveling wave solutions:

  • when a > 0
  • when a < 0
