摘要:

该文讨论了F -稳态映射的Liouville型定理, 并证明了当初始流形的截面曲率满足某些非正条件、F满足F-p -条件时, 具有有限F能量的F -稳态映射是常值映射. 作者也研究了一类特殊的F -稳态映射, 即服从积分F-守恒律的映射, 并证明了一个类似的Liouville型定理, 该定理的曲率假定和F-p -条件和上述定理相同, 但F -能量有限性被替换成更弱的F -能量慢发散条件.

关键词: F -稳态映射, Liouville型定理, F -调和映射

Abstract:

In this paper, the author discusses theorems of Liouville type for F-stationary maps, and proves that $F$-stationary maps with finite F-energy must be constant, if the sectional curvatures of the initial manifolds satisfy some nonpositive conditions and  F obeys the F-p-condition. The author also investigates a class of special F-stationary maps, i.e., maps obeying the integral F-conservation law, and proves similar theorems of Liouville type, under the same curvature conditions and the F-p-condition, but replacing the finiteness of F-energy by the slowly divergent F-energies.

Key words: F-stationary map, Theorem of Liouville type, F-harmonic map
