Part of the SpringerBriefs in Mathematics book series (BRIEFSMATH)


In this chapter, we present four theorems that will be proved and generalized in the body of the book. Each one gives a lower bound for the first eigenvalue of a weighted second-order ordinary differential equation, and they involve different integrals of the weight. The main aim of the book is to prove these theorems and show the interplay among them. We also present several extensions to nonlinear equations, systems, and more general operators, which are briefly described here.
