The Method of Upper, Lower Solutions and Volterra Integral Equations
(University of Texas at Arlington, 1980-12)
**Please note that the full text is embargoed** ABSTRACT: In employing the method of upper and lower solutions to dynamical systems, one is required to impose a certain monotone property on the given system [5,6,11] When ...
Periodic Solutions of Nonlinear Boundary Value Problems
(University of Texas at Arlington, 1980-04)
**Please note that the full text is embargoed** ABSTRACT: One of the well known techniques in the theory of nonlinear boundary value problems (BVP) is the method of differential inequalities or the method of upper and lower ...
