@article{Bilet_2012, title={Geodesic spaces tangent to metric spaces}, volume={64}, url={https://umj.imath.kiev.ua/index.php/umj/article/view/2657}, abstractNote={We investigate the geometry of spaces tangent and pretangent to general metric spaces with marked point. We find a sufficient condition under which every separable tangent space is geodesic. This condition is almost exact in the sense that it is necessarily satisfied if all spaces pretangent to a given metric space are geodesic.}, number={9}, journal={Ukrainsâ€™kyi Matematychnyi Zhurnal}, author={Bilet, V.
