具位势的次椭圆调和映射的稳定性

On stability of subelliptic harmonic maps with potential

Tian Chong, Yuxin Dong, Guilin Yang

摘要:

本文研究了具有位势的次椭圆调和映射的稳定性问题。首先,我们导出了带位势的次椭圆调和映射的第一和二阶变分公式。证明了当目标流形具有非正曲率且位势的Hessian非正定时,具有位势的次椭圆调和映射是稳定的。当目标流形为$\geq 3$维球面时,我们也给出了Leung型的结果,其中涉及到带位势的次椭圆调和映射的不稳定性。

英文摘要:

In this paper, we investigate the stability problem of subelliptic harmonic maps with potential. First, we derive the first and second variation formulas for subelliptic harmonic maps with potential. As a result, it is proved that a subelliptic harmonic map with potential is stable if the target manifold has nonpositive curvature and the Hessian of the potential is nonpositive definite. We also give Leung type results which involve the instability of subelliptic harmonic maps with potential when the target manifold is a sphere of dimension $\geq 3$.
