Aspects of Wave Interaction in Nonlinear Media

Sammanfattning: Selected aspects of various types of nonlinear wave interaction are investigated. These aspects are studied in terms of Nonlinear Schrödinger equations, mainly analytically and numerically, but also experimentally. The emphasis is on fundamental phenomena and mathematical methods, aiming to take full advantage of the formal analogies between different physical fields described in terms of similar nonlinear propagation equations. The thesis contains five appended papers.....
