      Menis, Alexandra Cristina (Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Matemática, 2009-08-11)
      In this work we study group gradings on the upper triangular matrices algebra UTn(F), which have several applications in the PI-algebra theory. Our main purpose is to exhibit a description of all _nite gradings of UTn(F) ...
