Nonlinear Bessel potentials and generalizations of the Kato Class


René Erlin Castillo

Universidad Nacional de Colombia, Colombia




We study the scale of function spaces Mp introduced by Zamboni. For these spaces, we get a characterization in terms of nonlinear Bessel potentials. This result is based on a known characterization of the Kato class Kn,s of order s in terms of Bessel potentials and the space of bounded uniformly continuous functions.


AMS Classification: 31C45.

Keywords :Kato class, Bessel potentials, nonlinear potential.
