Linear and Nonlinear Perturbations of the Operator div - Osmolovskii, V.G.
The perturbation theory for the operator div is of particular interest in the study of boundary-value problems for the general nonlinear equation $F(\dot y,y,x)=0$. This book presents results on boundary-value problems for $L$ and the theory of nonlinear perturbations of $L$.
