We deduce a formula for the affine curvature of a plane geodesic line on the affine hypersurface in terms of the affine
fundamental form and the shape operator. We present the definition of transverse curvature and determine some of its
elementary properties.}, number={4}, journal={Ukrainsâ€™kyi Matematychnyi Zhurnal}, author={ShuhayloO.}, year={2017}, month={Apr.}, pages={565-574} }
