Bifurcation analysis of a singular nonlinear Sturm-Liouville equation
A voluminous work about the existence of positive solutions for the singular Sturm-Liouville problem NEWLINE\[NEWLINE-(x^{2\alpha}u')' = \lambda u+u^{p}, u>0, u(1) = 0.NEWLINE\]NEWLINE Contrary to other works, the proofs do not rely on the change of variables. The author works directly with the equation.
