Variational methods and their generalizations have been verified to be useful tools in proving the existence of solutions to a variety of boundary value problems for ordinary, impulsive, and partial d
Topological Methods for Differential Equations and Inclusions covers the important topics involving topological methods in the theory of systems of differential equations. The equivalence between a co
This graduate textbook explains some of the early results on limit-point and limit-circle results for linear equations, such as those of Wintner, and various attempts at extensions to nonlinear eq
Mathematicians Graef (U. of Tennessee-Chattanooga), Henderson (Baylor U.), and Ouahab (Sidi-Bel-Abbes U., Algeria) explore differential equations that account for abrupt changes, such as shocks, harve
This book provides cutting-edge results on the existence of multiple positive periodic solutions of first-order functional differential equations. It demonstrates how the Leggett-Williams fixed-point
This book deals with the existence and stability of solutions to initial and boundary value problems for functional differential and integral equations and inclusions involving the Riemann-Liouville,
