In analysing nonlinear phenomena many mathematical models give rise to
problems for which only nonnegative solutions make sense. In the last
few years this discipline has grown dramatically. This state-of-the-art
volume offers the authors' recent work, reflecting some of the major
advances in the field as well as the diversity of the subject.
Audience: This volume will be of interest to graduate students and
researchers in mathematical analysis and its applications, whose work
involves ordinary differential equations, finite differences and
integral equations
