调和截面的随机刻画与一个Liouville定理

Stochastic characterization of harmonic sections and a Liouville theorem

S. N. Stelmastchuk

摘要:

设$P(M,G)$是主纤维束,而$E(M,N,G,P)$是缔合纤维丛。我们的兴趣是研究$E$到$M$的投影$π_{E}$的调和截面。本文的第一个目的是给出从$M$到$E$的调和截面的一个随机特征以及调和截面关于其等变升力的一个几何特征。第二个目的是给出调和截面的Liouville定理的一个版本,并证明截面$M$到$E$是调和截面当且仅当它是平行的。

英文摘要:

Let $P(M,G)$ be a principal fiber bundle and $E(M,N,G,P)$ be an associate fiber bundle. Our interested is to study harmonic sections of the projection $π_{E}$ of $E$ into $M$. Our first purpose is to give a stochastic characterization of harmonic section from $M$ into $E$ and a geometric characterization of harmonic sections with respect to its equivariant lift. The second purpose is to show a version of Liouville theorem for harmonic sections and to prove that section $M$ into $E$ is a harmonic section if and only if it is parallel.
