Positive Solutions of Semipositone BVPs for Differential Systems on Time Scales
Positive solution Semipositone boundary value problem Differential systems Time scales
font style='font-size:12px;'>
2011/10/12
The paper is concerned with the semipositone Sturm-Liouville-like boundary value problems of second-order differential systems on time scales with two parameters. Applying a fixed point theorem in con...
Weak Maximum Principle for Strongly Coupled Elliptic Differential Systems
Weak maximum principle strongly coupled elliptic system weak solution

2010/12/10
A classical counterexample due to E. De Giorgi, shows that the weak maximum principle
does not remain true for general linear elliptic differential systems. After that, there are some efforts to esta...

2008/11/26
In this paper, we establish existence, multiplicity and nonexistence of periodic solutions for a class
of first-order n-dimensional neutral functional differential equations. Our results improve the ...
A NOTE ON WEAKLY ISOTONE MAPS AND COMMON SOLUTIONS FOR DIFFERENTIAL SYSTEMS
Weakly isotone maps Differential equations Common solutions

2007/12/12
In this short note we examine the connection between weakly isotone maps and common solutions for first order Cauchy problems in ${\Bbb R}^n$ and, as a rule, in Banach lattices.
