Abstract

As the dynamics of fourdimensional magnetic monopoles requires
the introduction of an unobservable Diracstring, the dynamics
of magnetic extended objects in Mtheory requires the introduction
of an unobservable Diracbrane. There are, however, relevant situations
in Mtheory where the use of Diracbranes leads to inconsistencies.
After recalling the basic features of extended charges and monopoles in
Mtheory, the seminar describes these situations and presents a general
solution to the problem: Diracbranes have to be replaced with less singular
objects, so called Chernkernels.
