Query: Rational solutions from Pad\'e approximants for the generalized
  Hunter-Saxton equation   Exact rational solutions of the generalized Hunter-Saxton equation are
obtained using Pad\'e approximant approach for the traveling-wave and
self-similarity reduction. A larger class of algebraic solutions are also
obtained by extending a range of parameters within the solutions obtained by
this approach.
