Abstract
We give a characterization of the law of the partition function of a Brownian directed polymer model in terms of the eigenfunctions of the quantum Toda lattice. The proof is via a multidimensional generalization of theorem of Matsumoto and Yor concerning exponential functionals of Brownian motion.
