SUMMARY:Theory Keynote 2: Generation of magnetic field in the Sun and Star
 s. Why are we still arguing? - Steven Tobias (University of Leeds)

DESCRIPTION:In this talk I will review some of the theoretical issues faci
 ng dynamo theorists in explaining the origin of large-scale magnetic activ
 ity in the Sun and other solar-type stars. I will stress that the theoreti
 cal obstacles here are somewhat different from those that keep the geodyna
 mo community awake at night. Having given a brief introduction to the theo
 ry of turbulent statistical dynamos\, I will review the various "cartoon" 
 scenarios for solar dynamo action. I will finish by suggesting that a way 
 forward may be found in "Direct Statistical Simulation"\, though several t
 heoretical and computational hurdles remain to be addressed.
