Comparison Results for First and Second Order Boundary Value Problems at Resonance
(University of Texas at Arlington, 1982-05)
**Please note that the full text is embargoed** ABSTRACT: It is well known that the comparison principle for the initial value problems has been very useful in the theory of differential equations [1, 2,5]. Recently, such ...
On the Existence of Periodic Quasi Solutions for First Order Systems
(University of Texas at Arlington, 1982-09)
**Please note that the full text is embargoed** ABSTRACT: Recently the method of upper and lower solutions and Lyapunov-Schmitt
method have been fruitfully employed to prove the existence of periodic solutions for scalar ...
Comparison Results for Parabolic Differential Equations at Resonance
(University of Texas at Arlington, 1982-07)
**Please note that the full text is embargoed** ABSTRACT: It is very well known that comparison principles for initial and boundary value problems for nonresonance cases have been very much used in the existence of solutions
