AB  - In the present study, we obtain using the lever law of the lever, an explicit formula that allows to
calculate the center of mass of a system of n-particles with masses m<sub>1</sub>, m<sub>2</sub>, ..., m<sub>n</sub>>0, located on the half plane
superior of Lobachevsky H<sup>2</sup>, endowed with a conforming metric which induces constant and negative Gaussian
curvature.
