This IAU-symposium was the first which was entirely dedicated to
dynamo processes, which are fundamental on all cosmical scales.
Dynamo theory concerns one of the few truly key questions of recent
cosmic physics. There is increasing evidence for the magnetic
character of most short-term activity phenomena in astrophysics.
Obviously, the tria. ngle "gravil;y, nuclea. r power, magnetism"
dictates cosmic evolution over a very broad scale of magnitudes. A
complicated interplay of rotation, magnetism and turbulence, that
is hard to resolve, determines stellar and galactic activity for
almost all the short and medium time- scales. Behind these
multiform phenomena, the cosmic dynamo works in various guise. .
"I, all involving inductive and dissipative equilibria in rotating
turbulent cosmic plasmas. The Sun, representing the cosmic dynamo
par excellence, stands from the be- ginning at the centre of
interest for those who followed the dynamo idea. Even the first
models were able to present an explanation of the typical
structural appear- ance of the solar magnetic field, i. e. a 22
year cycle, activit. y belts and their zonal migration,
antisymmetry of t. he magnetic polarity. However, the solar dynamo
still provides topics of further discussions, since confrontation
with recent observational data raised and stoill raises new
questions, nOll of whicll have yet found a plausible answer. These
questions represent a challenge for the development of the basic
the- ories: Understanding of turbulence, especially Ilsing methods
of modern nonlinear physics. Numerical simulations arc promising in
the ncar future.
