*"Higher order Gauss maps"*

Abstract. The Gauss map is an important and fundamental tool in 
algebraic and differential geometry.
We will present  generalisations, so called higher order Gauss maps, 
capturing higher order local positivity and tangency.
The main goal of the talk is to explain these (rational) maps and to 
show that, if the variety is smooth and the Gauss map of order
k is a regular map, than it is finite except in the case of the k-th 
Veronese embedding. This is a straight forward generalisation of
the classical case. If time permits a toric interpretation will be 
presented. This is joint work with A. Lundman and K. Jabbusch.
