‎In this paper‎, ‎we study a class of boundary value problem‎ ‎involving the p-Laplacian oprator and singular nonlinearities‎. ‎We‎ ‎analyze the existence a critical parameter $lambda^{ast}$ such‎ ‎that the problem has least one solution for‎ ‎$lambdain(0,lambda^{ast})$ and no solution for‎ ‎$lambda>lambda^{ast}.$ We find lower bounds of critical‎ ‎parameter $lambda^{ast}$‎. ‎We use the method ...

In this paper , by constructing a special set and utilizing fixed point theory in coin , we study the existence of solution of singular two points boundary value problem for second-order differential equation , which improved and generalize the result of related paper . Keywords—singular differential equation , boundary value problem, coin , fixed point theory .
