We study harmonic Bergman functions on the unit ball B in Rn. Among our main results are: For the Bergman kernel Kα(x, y) of the orthogonal projection Pαof L2,α-1onto the harmonic Bergman space l2,α-1the following estimate holds: $$\left| {K_\alpha (x,y)} \right| = O\left( {\left| {x - y} \right|^{ - n + 1 - \alpha } } \right),{\text{ }}x \in B,{\text{ }}y \in \partial B$$ . The Bergman projection Pαis bounded for the range 1 < p < ∞. Also, Pαmaps L∞onto the harmonic Bloch space B∞and C0(B) onto the little harmonic Bloch space B0. The duals of the harmonic Bergman spaces lp,α-1are calculated for all p > 0 and α > 0.
