Nonlinear Conditions for Ultradifferentiability
A remarkable theorem of Joris states that a function f is [Formula: see text] if two relatively prime powers of f are [Formula: see text] . Recently, Thilliez showed that an analogous theorem holds in Denjoy–Carleman classes of Roumieu type. We prove that a division property, equivalent to Joris’s r...
