This book examines various mathematical tools-based on generalized collocation methods-to solve nonlinear problems related to partial differential and integrodifferential equations. Covered are specific problems and models related to vehicular traffic flow, population dynamics, wave phenomena, heat convection and diffusion, transport phenomena, and pollution.
