Isometries of comlplex hyperbolic plane
Complex Hyperbolic Plane, Isometries of complex Hyperbolic plane .
The main goal of this work is to classify the isometries of complex hyperbolic
plane
H^2_C
by studying their fixed points. To this end, we introduce H ^2_C as an open set of
complex projective plane. We study the disc model, the Siegel domain, and horospherical
coordinates to understand its distance function, the Bergman metric, its isometry group
P U (2, 1), and its totally geodesic submanifolds. The elements of PU (2, 1) will be seen as
collineations induced by matrices of SU (2, 1), so the classification will be done through
the study of the eigenvalues of such matrices.
