Classification of partial differential equations: a survey of some results
Abstract:
We give an account of aspects pointsymmetry classification of
quasilinear evolution equations in 1+1 dimensions. This type of
classification is based on the use of the equivalence group (given in
finite form) together with the Lie algorithm for testing admissibility
of given Lie algebras as symmetry algebras of evolution equations (of a
given order).
