Résumé: We study the three-dimensional joint distribution of a Brownian motion and the integrals of its exponentials from some points of view. We show an explicit expression of the Laplace transform of the distribution and the result gives an extension of Yor's result on the two-dimensional one. We apply the result to some problems, in particular, to the calculation of an explicit form of the heat kernel of the semigroup generated by the Maass Laplacian on the Poincaré upper half plane.
