Similarity Solutions for the Complex Burgers' Hierarchy

A detailed analysis of the invariant point transformations for the first four partial differential equations which belong to the complex Burgers' hierarchy is performed. Moreover, a detailed application of the reduction process through the Lie-point symmetries is presented while we construct the similarity solutions. We conclude that the differential equations of our consideration are reduced to first-order equations such as the Abel, Riccati, and to a linearisable second-order differential equation by using similarity transformations.
