For a complete ortho-normal system φ（t） = （φ0（t）, φ1（t）, φ2（t）, ） of L2H（D）, the space of the holomorphic and absolutely square integrable functions in the bounded domain D of Cn, φ（t）, t ∈ D, is considered as the homogeneous coordinate of a point in CP∞. The correspondence t →φ（t） induces a holomorphic imbedding ιφ ： D → CP∞. It is proved that the Bergman kernel K（t, v） of D equals to zero for the two points t and v in D if and only if their image points under ιφ are conjugate points of CP∞.展开更多

Because domain WIII is neither homogeneous domain nor Reinhardt domain, we will use a new way to solve this problem. First, we give a holomorphic automorphism group, such that for any Zo, there exists an element of this group, which maps (W, Zo) into (W,O). Second, introduce the concept of semi-Reinhardt and discuss the complete orthonormal system of this domain.展开更多
