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 ...
Existence criteria for singular boundary value problems with sign changing nonlinearities

Singular positone and semipositone boundary value problems of second order delay differential equations
(Institute of Mathematics, Czech Academy of Sciences, 2005-06-01)
In this paper we present some new existence results for singular positone and semipositone boundary value problems of second order delay differential equations. Throughout our nonlinearity may be singular in its dependent ...
Solutions of a system of integral equations in orlicz spaces
(Rocky Mountain Mathematics Consortium, 2009-12-01)
We consider the following system of integral equations
u(i)(t) = integral(1)(0) g(i)(t, s)f(i) (s, u(1)(s), u(2)(s),...,u(n)(s)) ds,
a.e. t is an element of [0,1]. 1 <= i <= n.
Our aim is to establish criteria ...
