Non-Fuchsian extension to the Painlev\'e test
Abstract
We consider meromorphic particular solutions of nonlinear ordinary differential equations and perform a perturbation \`a la Poincar\'e making their linearized equation non-Fuchsian at the movable pole and Fuchsian at infinity. When the nonlinear equation possesses movable logarithms, they are detected sooner than with the perturbative (Fuchsian) Painlev\'e test.
