  The article reviews some of the (fairly scattered) information available in
the mathematical literature on the subject of angles in complex vector spaces.
The following angles and their relations are considered: Euclidean, complex,
and Hermitian angles, (Kasner's) pseudo-angle, the Kaehler angle (synonyms for
the latter used in the literature are: angle of inclination, characteristic
deviation, holomorphic deviation, holomorphy angle, Wirtinger angle, slant
angle).
