It is shown there that $(M, \nabla \ ) $ is flat or of recurrent curvature. And if $f$ is additionally umbilical with non-zero shape tensor and dim $M \ge \ 3$, then $(M, \nabla \ ) $ is locally projectively flat.
In the presented paper, the investigation of totally geodesic affine immersions is continued. We assume that the ambient manifold $( \bar M \ , \bar \nabla \ ) $ is of recurrent projective curvature. It is proved that if dim $M \ge \ 3$, then $(M, \nabla \ ) $ is locally projectively flat or of recurrent projective curvature. Moreover, if $f$ is additionally umbilical with non-zero shape tensor, then $(M, \nabla \ ) $ is locally projectivvely flat.Zbigniew Olszak
