Existence theory for single and multiple solutions to singular positone boundary value problems
(Elsevier BV, 2001-09-01)
Existence results of brezis-browder type for systems of fredholm integral equations
(Springer Nature, 2011-01-01)
In this article, we consider the following systems of Fredholm integral equations: [GRAPHICS] Using an argument originating from Brezis and Browder [Bull. Am. Math. Soc. 81, 73-78 (1975)] and a fixed point theorem, we ...
Fixed point theorems for convex-power condensing operators relative to the weak topology and appli- cations to volterra integral equations
(Rocky Mountain Mathematics Consortium, 2012-06-01)
In this paper we present new fixed point theorems for weakly sequentially continuous mappings which are convex-power condensing relative to a measure of weak noncompactness. Our fixed point results extend and improve several ...
Controllability of nonlinear delay oscillating systems
(University of Szeged, 2017-01-01)
In this paper, we study the controllability of a system governed by second order delay differential equations. We introduce a delay Gramian matrix involving the delayed matrix sine, which is used to establish sufficient ...
Positive solutions to superlinear singular boundary value problems

Some new results for singular problems with sign changing nonlinearities

On constant-sign periodic solutions in modelling the spread of interdependent epidemics
(Cambridge University Press (CUP), 2006-01-01)
We consider the following model that describes the spread of n types of epidemics which are interdependent on each other: u(i)(t) = integral(t)(t-r) g(i)(t, s) f(i) (s, u(1)(s), u(2)(s),..., u(n)(s))ds, t is an element of ...
