摘要

We showed in [3] and [4] the variation formulas for Schif-fer spans and harmonic spans of the moving domain D(t) in C_z with parameter t ∈ B = {t ∈ C_t : t < p}, respectively, such that each aD(t) consists of a finite number of C~ω contours C_j (t) (j = 1...,v) in C_z and each C_j(t) varies C~ω smoothly with t ∈ B. This implied that, if the total space D = ∪_(t∈B)(t, D(t)) is pseudoconvex in B× C_z, then the Schiffer span is logarithmically subharmonic and the harmonic span is subharmonic on B, respectively, so that we showed those applications. In this paper, we give the indispensable condition for generalizing these results to Stein manifolds. Precisely, we study the general variation under pseudoconvexity, i.e., the variation of domains D : t ∈ B → D(t) is pseudoconvex in B × C_z but neither each aD(t) is smooth nor the variation is smooth for t ∈ B.
