Resumo(s)

In this paper we consider the monoid (Formula presented.) of all partial isometries of a star graph Sn with n vertices. Our main objectives are to determine the rank and to exhibit a presentation of (Formula presented.). We also describe Green’s relations of (Formula presented.) and calculate its cardinal.
