Title: Geometric means of positive definite matrices


Abstract:  In this talk, first of all we will recall some ideas that led 
to the definition of the geometric mean of two positive definite 
matrices. Then, we will see how this geometric mean is related with the 
complex interpolation method, with the Riemannian structure of the cone 
of positive definite matrices, and finally, with recent results about 
barycenters in metric spaces with negative curvature.
