Abstract:

The existence of the positive solutions to the Sturm-Liouville problem in Banach spaces is discussed  in the  superlinear or sublinear case by using the fixed point theory of condensing mapping and doing precise computation of measure of noncompactess and using the eigenvalues corresponding to the relevant linear equations.

Key words: Boundary value problem, Measure of noncompactness, Fixed point index, Positive solution
