Twin positive periodic solutions of second order singular differential systems
(Uniwersytet Mikolaja Kopernika/Nicolaus Copernicus University, 2005-06-01)
In this paper, we study positive periodic solutions to singular second order differential systems. It is proved that such a problem has at least two positive periodic solutions. The proof relies on a nonlinear alternative ...
Existence criteria for singular initial value problems with sign changing nonlinearities
(Hindawi Limited, 2001-01-01)
A general existence theory is presented for initial value problems where our nonlinearity may be singular in its dependent variable and may also change sign.
Solvability of singular dirichlet boundary-value problems with given maximal values for positive solutions
(Cambridge University Press (CUP), 2005-02-01)
The singular boundary-value problem (g(x'(t)))' = muf (t, x(t), x'(t)), x(0) = x(T) = 0 and max {x(t) : 0 less than or equal to t less than or equal to T} = A is considered. Here p is the parameter and the negative function ...
