On a classification of almost geodesic mappings of affine connection spaces. (English) Zbl 0964.53011

Summary: A classification of almost geodesic mappings is given. It is proved that, if an almost geodesic mapping \(f\) is simultaneously \(\pi_1\) and \(\pi_2\) (or \(\pi_3\)), then \(f\) is a mapping of affine connection spaces with preserved linear (or quadratic) complex of geodesic lines.
