DESCRIPTION:Jasmin Matz (Einstein Institute of Mathematics Hebrew Universi
 ty of Jerusalem)\nLet G be a semisimple Lie group with unitary dual ^G\, a
 nd L a co-finite lattice in G. L can be used to define a measure m_L on ^G
  in a natural way. A natural question is\, whether m_L tends to the Planch
 erel measure on ^G if L varies over a family of co-finite lattices with vo
 l(L\\G)->infinity. This has been proven to be true in many situations in w
 hich the lattices are either commensurable with each other\, uniform in G\
 , or G=SL(2\,R) or SL(2\,C). In my talk I want to discuss this problem for
  the natural family of lattices SL(O_F) in G = SL(2\,R)^r+SL(2\,C)^s when 
 F runs over all number fields with fixed archimedean signature (r\,s) and 
 O_F is the ring of integers in F.
