Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

On a New Symmetry Method, with Application to the Nonlinear Heat Equation

ABSTRACT: We determine the group invariant solutions of the nonlinear heat equation though the linear case, using a relation that exists between the two. This is not new, but there has always been those solutions that proved difficult to evaluate through existing symmetry techniques, for both linear and nonlinear cases. We introduce what we call modified Lie symmetries to address these difficulties

KEYWORDS: Group method; Heat diffusion; Nonlinear problems; Modified symmetries
