The problem of realizing the Lobachevsky geometry in Euclidean space,idean space. In particular, we give an exposition of Lobachevsky planimetry as the geometry of a two-dimensional Riemannian manifold of constant negative curvature.We describe the apparatus of fundamental systems of equations of the theory of surfaces in . and discuss specifics of its application to

The sine-Gordon equation: its geometry and applications of current interest,olic geometry) nonlinear equation that has wide applications in contemporary mathematical physics. A far-reaching fact that enables the realization of diverse approaches to the investigation of problems connected with the sine-Gordon equation is the intimate association of this equation with surface

Lobachevsky geometry and nonlinear equations of mathematical physics,rdinate nets on the Lobachevsky plane ..We introduce the class of Lobachevsky differential equations (.-class), which admit the aforementioned interpretation. The development of this geometric approach to nonlinear equations of contemporary mathematical physics enables us to apply in their study the
