The aim of this paper is to describe the largest inscribed circle into the fundamental domains of a discontinuous group in Bolyai-Lobachevsky hyperbolic plane. We give some known basic facts related to the Poincare-Delone problem and the existence notion ... see more

In this paper, we present two gyroarea formulas (Möbius-Bretschneider’s formula and Möbius-Cagnoli’s formula) for Möbius gyroquadrilaterals in the Poincaré disc model of hyperbolic geometry.

In this paper, we study a mixed problem for a third order hyperbolic equation with non classical boundary condition. We prove the existence and uniqueness of the solution. The proof of the uniqueness is based on a priori estimate and the existence is esta... see more

The hyperbolic distribution has four parameters and the logarithm of its probability density function is a hyperbola. The distribution has been used to analyze data from different scientific areas and in particular data from earth science. Some of the mos... see more

In this paper, we consider the linear system of partial differential equations hyperbolic type Which is solved by  T.V. Chekmarev [1] and solve the general form for this Hyperbolic type.

The problem of integrated navigation complex structure is discussed. The hyperbolicand satellite navigation systems are proposed to be the consisting parts of such a complex. Theproblem of their integration is solved
