Topic: 

C* Algebras Associated with Number Fields

Description: 

We will first present the algebras A(K) associated with a number field K
which were introduced and analyzed in joint work with X.Li. The
computation of their K-theory is a challenging problem. It turns out to
be determined by the multiplicative group of the field. The requirement
of functoriality of the construction leads to a canonical "Toeplitz
type"-extension of the algebra A(K) which very closely reflects the
structure of the number field K (zeta-function, class number etc.). We
will then discuss this new type of algebra in detail.
