[cmath] The 2006 Ribenboim Prize

[David Boyd]

  The Ribenboim Prize committee is pleased to announce that the 2006
  Ribenboim Prize has been awarded to Vinayak Vatsal of the University of
British Columbia.  Vatsal has made fundamental contributions to the
Iwasawa Theory of elliptic curves, introducing profound techniques from
ergodic theory into the subject and obtaining startling  theorems on the
non-vanishing of $p$-adic L-functions and mu-invariants that had
previously been unobtainable by more orthodox analytic methods.  In the
words of his nominators,  his results have ``transformed our understanding
of the ranks of elliptic curves in towers of number fields''.     Vatsal 
will present a plenary lecture on his work at the upcoming conference of 
the Canadian Number Theory Association in Vancouver, July 9-14, 2006.
