Diffeomorphism cohomology and gravitational anomalies.—II

Когомология и гравитационные аномалии.—II

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

Using the spectral sequencies technique, we study the local polynomial cohomology space of the operatorS LΓc1 −Cλ(x λ λ C λ(x), which is isomorphic to the local functional cohomology of the operator δ LΓc1 which induces general co-ordinate transformations in four-dimensional space-time. In the Faddeev-Popov (ΦII) charge-one sector, we find that all the anomalies have the form\(\Delta (x) = \partial _\lambda C^\lambda (x)\hat \Delta (x)\) whereC λ(x) is the ghost field, and\(\hat \Delta (x)\) is a ΦII charge-zero anomaly.

Riassunto

Usando la tecnica delle sequenze spettrali, studiamo la coomologia nello spazio dei polinomi locali dell’operatoreS LΓc1 −Cλ(x λ λ C λ(x), che è isomorfa alla coomologia sui funzionali locali dell’operatore δ LΓc1 , che induce trasformazioni generalizzate di coordinate in uno spazio-tempo a quattro dimensioni. Nel settore di carica di Faddeev-Popov eguale a uno, noi troviamo che tutte le anomalie hanno la forma\(\Delta (x) = \partial _\lambda C^\lambda (x)\hat \Delta (x)\), doveC λ(x) è il campo fantasma e\(\hat \Delta (x)\) è un’anomalia di carica zero.

Резюме

Используя технику спектральных последовательностей, мы исследуем когомологию в пространстве локальных полиномов оператораS LΓc1 −Cλ(x λ λ C λ(x), который является изоморфным когомологии локальных функционалов оператора δ LΓc1 , который индуцирует общие преобразования координат в четырехмерном пространстве-времени. В секторе фадеева-Попова с зарядом единица получается, что все аномалии имеют вид\(\Delta (x) = \partial _\lambda C^\lambda (x)\hat \Delta (x)\), гдеC λ(x)есть поле «духов», а\(\hat \Delta (x)\) есть аномалия для заряда нуль.
