By employing a well-known fixed point index theorem and combining with a varication substitution, we study the existence of positive solutions for a singular semipositone differential system. A new existence result is established, which is in essence different from the known results. An example is p

The paper presents sufficient conditions for the existence of positive solutions to the singular boundary value problem I" = pq(t)f(t, z,z'), W(O) -&T'(O) = a > 0, z(T) = 0 with q > 0 on (O,T), f 2 0 on a suitable subset of (O,T] x (0,oo) x R which may be singular at z = 0 and where either a, p E (0
