Matchings and the variance of Lipschitz functions
ESAIM: Probability and Statistics, Tome 13 (2009), pp. 400-408.

We are interested in the rate function of the moderate deviation principle for the two-sample matching problem. This is related to the determination of 1-Lipschitz functions with maximal variance. We give an exact solution for random variables which have normal law, or are uniformly distributed on the euclidean ball.
