German Universities have no regular formalized PhD program.
These were concerned with structural properties in Nonlinear Dynamics. There will be more PhD's in the future, these then will be more in the heart of Symbolic Computation and on the level of system design. Apart from the activity which I described we had several MS's in that field. Right now we are designing and implementing a general-purpose system which is based on parallel computation.
