Uniqueness of the first eigenfunction for fully nonlinear equations: the radial case
Summary: The concept of eigenvalue has recently been extended to a large class of fully-nonlinear operators, here for fully-nonlinear operators in non divergence form that present singularities and degeneracies similar to the \(p\)-Laplacian we prove that in the radial case the eigenfunction is simple.
