In this paper, group analysis of the time fractional Harry-Dym equation with Riemann–Liouville derivative is performed. Its maximal symmetry group in Lie’s sense and the corresponding optimal system of subgroups are determined. Similarity reductions of the equation under study are performed....

We perform Galilei symmetry group classification of a class of third-order nonlinear evolution equations in one spatial variable, which generalize KdV and mKdV equations. All inequivalent PDEs belonging to the class in question which admit the classical Galilei group, the extended Galilei group...

Many steps in the creation and dissemination of new accounting standards lag behind the rest of the modern world. Issues are often addressed too late to rectify major problems, in language at once too vague to deal effectively with the nuances of real world business decisions, and too lengthy to...

Purpose –The audit of corporations is now dependent on the examination of corporate computer systems. Although tools and techniques have been available for decades, there are major limitations on the audits of corporate systems by external auditors. This paper aims to examine external auditor...
