摘要: 设(M1,g) 和(M2,h) 是两个埃尔米特流形,挠积埃尔米特流形(M1×fM2,G) 是赋予了埃尔米特度量 G = g+f2h 的乘积流形M1×M2，这里f是M1×M2上的光滑函数。本文推导出挠积埃尔米特流形的挠率和挠率(1,0)形式，给出埃尔米特流形(M1×fM2,G)平衡的充分必要条件。
Abstract: Let (M1,g) and (M2,h) be two Hermitian manifolds. The twisted product Hermitian manifold (M1×fM2,G) is the product manifold M1×M2 endowed with the Hermitian metric G = g+f2h , where f is a positive smooth function on M1×M2. In this paper, the torsion tensor and torsion (1,0) forms of the twisted product Hermitian manifold are derived. Sufficient and necessary conditions are given that (M1×fM2,G) is balanced.
