*B*+

*G*of two operators, where

*B*is a linear or nonlinear operator and

*G*is a multivalued operator. The results extend previous ones of this type.

*n*≥2. At the end of the chapter, the results are applied to the sublinear Thomas-Fermi equation.

*L*

^{2}solution to a nonlinear equation, but our focus throughout this work is on results that imply that all solutions have this or an analogous property.
