### Historical Examples of lobachevski

Lobachevski has proved not, by creating non-Euclidean geometry.

There is a sort of opposition between Riemann's geometry and that of Lobachevski.

Thus, however far the consequences of Lobachevski's hypotheses are pushed, they will never lead to a contradiction.

The two-dimensional geometries of Riemann and Lobachevski are thus correlated to the Euclidean geometry.

Beltrami has shown that the geometry of these surfaces is none other than that of Lobachevski.
