## Abstract The purpose of the present paper is twofold. The first object is to study the Laplace equation with inhomogeneous Dirichlet and Neumann boundary conditions in the half‐space of ℝ^__N__^. The behaviour of solutions at infinity is described by means of a family of weighted Sobolev spaces.

Abstract
For a prime number p, let Q~p~ be the p ‐adic field and let Q~p~ ^d^ denote a vector space over Q~p~ which consists of all d ‐tuples of Q~p~ . Then we study the p ‐adic version of the Calderón–Zygmund decomposition, Carleson measures on the vector space Q~p~ ^d +1^ and the space BMO (Q~p~ ^d^ ) of functions of bounded mean oscillation on Q~p~ ^d^ . In particular, it turns out that the operator norms of various oncoming operators are independent of the dimension d and the prime number p, which is one of the big differences from that of the Euclidean case. Interestingly, the independence of the dimension d and p makes it possible to develop Harmonic Analysis on the infinite dimensional p ‐adic vector space as the importance had already been pointed out in the Euclidean case (© 2009 WILEY‐VCH Verlag GmbH & Co.

## Abstract The space of probability measures on a Riemannian manifold is endowed with the Fisher information metric. In [4] T. Friedrich showed that this space admits also Poisson structures {, }. In this note, we give directly another proof for the structure {, } being Poisson. (© 2007 WILEY‐VCH
Let V = V(n,q) denote the vector space of dimension n over GF(q). A set of subspaces of V is called a partition of V if every nonzero vector in V is contained in exactly one subspace of V. Given a partition P of V with exactly a i subspaces of dimension i for 1 ≤ i ≤ n, we have n i=1 a i (q i -1) =
