Resumo

Provamos que existe uma correspondência um para um entre as ações parciais de um grupoide G sobre um conjunto X e as ações de semigrupoide inverso do semigrupoide inverso de Exel S(G) sobre X. Também definimos representações de semigrupoide inverso sobre um espaço de Hilbert H, bem como a C*-álgebra grupoide parcial de Exel C*_p(G), e provamos que existe uma correspondência um para um entre representações parciais de grupoide de G sobre H, representações de semigrupoide inverso de S(G) sobre H e representações de C*-álgebra de C*_p(G) sobre H.
