Query: Lipschitz type spaces and Landau-Bloch type theorems for harmonic
  functions and Poisson equations   In this paper, we investigate some properties on harmonic functions and
solutions to Poisson equations. First, we will discuss the Lipschitz type
spaces on harmonic functions. Secondly, we establish the Schwarz-Pick lemma for
harmonic functions in the unit ball $\IB^n$ of $\IR^n$, and then we apply it to
obtain a Bloch theorem for harmonic functions in Hardy spaces. At last, we use
a normal family argument to extend the Landau-Bloch type theorem to functions
which are solutions to Poisson equations.
