DESCRIPTION:A lattice L in a semisimple Lie group G is a discrete subgroup\nof G for which the quotient L\G has finite volume. One may\nconstruct lattices using number theory and such lattices are\nsaid to be ""arithmetic"". Lattices that cannot be constructed\nin this way are called ""non-arithmetic"" are hard to find.\nIn this talk we focus on the case where G=3DSU(n,1). The first\nnon-arithmetic lattices in SU(2,1) were constructed by\nMostow in 1980. Subsequently Deligne and Mostow found a\nfamily of non-arithmetic lattices in SU(2,1) and a single\nexample in SU(3,1). <br />\n[Invited by R. Kellerhals and J. Paupert]
