“…In the case of Kogut-Susskind ("staggered") fermions the projection to a single Dirac fermion species can be defined in momentum space (Sharatchandra et al , 1981) or locally in coordinate space (Gliozzi, 1982;Kluberg-Stern et al , 1983; see also Kitazoe et al , 1978). In order to construct appropriate local hadron operators, one must first classify lattice operators according to the irreducible representations of the full lattice symmetry group of the staggered fermions (Golterman and Smit, 1984aMorel and Rodrigues, 1984;Parisi and Cheng, 1984;Golterman, 1986;Joos, 1986). Next one would like to know how these representations are imbedded in the representations of the continuum symmetry and whether the symmetries broken by the lattice regularization are restored at all in the continuum limit.…”

“…Staggered fermions are equivalent to Dirac-Kähler fermions and correspond to four Dirac flavors per staggered species at the vanishing gauge coupling of the Gaussian FP [25][26][27]. The renormalized trajectory (RT) that originates from the GFP preserves this property, so N s staggered fermions describe 4N s Dirac flavors around the GFP, and even at the IRFP, if the system is conformal.…”

“…O estudo de formulações multivetoriais da equação de Dirac tem-se mostrado um objeto de interesse recorrente, com motivações tanto físicas quanto matemáticas. Como exemplos, podemos citar os trabalhos de Ivanenko, Fock e Landau (1928), Proca (1930), Eddington (1948), Schönberg (1951), Kähler (1962) e Hestenes (1967), além de várias tentativas de discretização de férmions em redes, através da equação de Dirac-Kähler [Bec82,Joo86,Rab82,Lin90,Lin91]. De uma maneira geral, tais estudos têm a característica comum de buscar uma representação de campos espinoriais por meio de entidades geométricas, num sentido que pretendemos tornar mais preciso adiante.…”

“…De fato, no contexto de espaço-tempo chato é possível considerar identificações (não-canônicas) entre formas diferenciais e espinores, no sentido mencionado acima. Nestas circunstâncias, a EDK se decompõe em quatro equações de Dirac desacopladas, definidas em ideais à esquerda minimais de Cℓ 1,3 (C) [Bec82,Joo86,Rab82,Lin90,Lin91]. Além disso, a arbitrariedade na escolha dos ideais -usados para decompor a EDK em quatro cópias da equação de Diracconstitui uma simetria global do sistema.…”
