Abstract:

Two points of the infinite dimensional complex projective space CP∞ with homogeneous coordinates α=(α0, α1, α2) and b=b0, b1b2), respectively, are conjugate if and only if they are complex orthogonal, i.e., αb = Σj=0
αbj =0. 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 Cnφ(t), t ∈ D, is considered as the homogeneous coordinate of a point in CP. The correspondence t → φ(t) induces a holomorphic imbedding tφ 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 tφ are conjugate points of CP.

Key words: conjugate points, Bergman kernel
