Abstract
In this paper an attempt was made in establishing isomorphisms between some usual elds as elds of rational numbers, real numbers, complex numbers and the set of rhotrices de ned over these elds. The purpose was to explore relationships between these structures (the usual elds) and the structure of rhotrices de ned over them and between their properties. Some existing mathematical concepts were discussed with the aid of the new structures (rhotrices de ned over the usual elds) and the relationships so established between those elds and those rhotrices.
