Nonlinear Wave Equations

Establishes the complete lower bound estimates of lifespan for classical solutions to the Cauchy problem of nonlinear wave equations with small initial data in all possible space dimensions

Proposes the global iteration method, which offers a unified and straightforward approach to the problems

Accompanies readers fro m the basics to the latest advances in the field
