This is an announcement for the paper "A note on a non-linear Krein-Rutman theorem" by Rajesh Mahadevan. Abstract: In this note we will present an extension of the Krein-Rutman theorem for an abstract nonlinear, compact, positively 1-homogeneous, monotone non-decreasing operators on a Banach space and apply the result to many nonlinear elliptic partial differential operators.
