In this paper, we study the existence of positive solutions for singular impulsive differential equations with integral boundary conditions {u″(t) + q(t)f(t, u(t), u′(t)) = 0, t ϵ J′, Δu(tk) = Ik(u(tk), u′(tk)), k = 1, 2, ⋯ ,p, Δu′(tk) = -Lk(u(tk), u′(tk)),k = 1, 2, ⋯ ,p, u(0) = ∫0¹ g(t)u(t)dt, u′(1) = 0, where the nonlinearity f(t, u, v) may be singular at u = 0 and v = 0. The proof is based on the theory of Leray-Schauder degree, together with a truncation technique. Some recent results in the literature are generalized and improved. [ABSTRACT FROM AUTHOR]
