Suppose D ⊂ Cn is a smoothly
bounded domain and u is bounded and pluriharmonic in D. Let u∗ denote the
boundary function of u, and let ζ0∈ ∂D. It is shown that if u∗ has good averaging
behavior on one curve in ∂D through ζ0, then u∗ has good averaging behavior on all
curves in ∂D through ζ0, provided the curves in question satisfy a certain
directional condition. These results fail if the directional condition on the curve is
violated.
