Number representation and symbolic dynamics
Abstract: In this talk we will focus on the properties of the symbolic dynamical
systems arising from the representation of numbers in a given base \beta. We
will be particularly interested in the case where the representation of a given
number is not unique:  \beta=2 and digits 1, 0 and 1;  \beta>1 is not an
integer. We will present old and new results on the properties of the socalled
\beta shift.
Refreshments will be served at 2:45 p.m. in the Faculty Lounge,
Math Annex (Room 1115).
