Existence of positive radial solutions for a weakly coupled system via blow up [PDF]
Abstract and Applied Analysis, 1998 The existence of positive solutions to certain systems of ordinary differential equations is studied. Particular forms of these systems are satisfied by radial solutions of associated partial differential equations.

Morse index and uniqueness for positive solutions of radial $p$-Laplace equations [PDF]
Transactions of the American Mathematical Society, 2004 The authors consider positive radial solutions to a radial \(p\)-Laplace equation on the unit ball with Dirichlet boundary conditions. Using the spectrum of the linearized operator in a weighted space of radial functions, they derive the Morse index and use it to prove uniqueness and nondegeneracy in some particular cases.
