Research output: Contribution to journalArticlepeer-review


Lie symmetries of K (m n ) equations with time-dependent coefficients ate classified Group classification is presented up to widest possible equivalence groups the usuil equivalence group of the whole class for the general case and the conditional equivalence groups for special values of the exponents m and n Examples on reduction of K (m n) equations (wiih inicial and boundaiy conditions) to nonlinear ordinary diflerenual equations (wiih inicial condilions) are presented.
