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 and multiplicity of solutions for some three-point nonlinear boundary value problems
(Springer Nature, 2006-01-01)
We study the existence and multiplicity of solutions for the three-point nonlinear boundary value problem u '' ( t) +lambda a(t) f (u) = 0, 0 < t < 1; u( 0) = 0 = u(1)-gamma u(eta), where eta is an element of (0,1), ...
