The sphere and the cut locus at a tangency point in two-dimensional almost-Riemannian geometry

open access: yes, 2010
We study the tangential case in 2-dimensional almost-Riemannian geometry. We analyse the connection with the Martinet case in sub-Riemannian geometry. We compute estimations of the exponential map which allow us to describe the conjugate locus and the ...

THE EINSTEIN GENERALIZED RIEMANNIAN GEOMETRY [PDF]

open access: yesProceedings of the National Academy of Sciences, 1963
It is shown that the generalized Hiemann tensor can be derived from Einstein's equations that relate the nonsymmetric covariant metric tensor of the space-time continuum of four dimensions and the contravariant tensor. (C.E.S.)
