"Stochastic algorithms for computing means of probability measures".
Abstract : Consider a probability measure supported by a regular
geodesic ball in a manifold. For any p larger than or equal to 1 we
define a stochastic algorithm which converges almost surely to the p-
mean of the measure. Assuming furthermore that the functional to
minimize is regular around the p-mean, we prove that a natural
renormalization of the inhomogeneous Markov chain converges in law
into an inhomogeneous diffusion process. We give an explicit
expression of this process, as well as its local characteristic.
