This book presents current research in the field of applied mathematics. Topics discussed include non-gauge invariant cubic non-linear schrodinger equations; geometric aspects of sturm-liouville problems; soliton perturbation theory for the generalised equal width equation; general non-linear variational-like inequality in reflexive banach spaces; and, travelling wave solitons of the generalised BBM equation and quarter-plane problems for the kawahara equation.

This book presents current research in the field of applied mathematics. Topics discussed include dual bounds in convex and nonconvex differentiable optimisation problems and applications; direct numerical simulation; analysis and classification of the irregulat koch curve; interface wave diffraction by a thin vertical barrier; cross-range imaging of synthetic aperture radar data; and integrability and prlongation structure of a generalised korteweg-de vries equation.
