DESCRIPTION:Using the coherent state transform Wehrl (1979) suggested a de
 finition of the classical entropy of a quantum state. He conjectured that 
 the classical entropy was minimized by coherent states\, i.e.\, the states
  that also minimize the Heisenberg uncertainty inequality. Lieb (1978) pro
 ved this conjecture and at the same time conjectured that the same would b
 e correct for the Bloch coherent states of all the irreducible SU(2) spin 
 representations. This generalized Wehrl conjecture has been open for almos
 t 35 years. I will present a short proof of the conjecture. This is joint 
 work with E.H. Lieb.\n
