本文给出了对称双圆盘G的所有复测地线的计算公式。有两类测地线:平坦测地线,由单位圆盘索引; 2次测地线,自然由G本身索引。平坦测地线使G叶状,并且存在唯一的测地线通过G的每对点。我们还得到了复测地线左逆的一个可分性结果。
We give formulae for all complex geodesics of the symmetrized bidisc G. There are two classes of geodesics: flat ones, indexed by the unit disc, and geodesics of degree 2, naturally indexed by G itself. The flat geodesics foliate G, and there is a unique geodesic through every pair of points of G. We also obtain a trichotomy result for left inverses of complex geodesics.
