Conformal algebra in two space-time dimensions and the thirring model

Конформная алгебра в двух пространствен но-временных иэмерениях и модель Тирринга

Summary

The-infinitesimal generators of the infinite-dimensional conformal algebra in two space-time dimensions are constructed from the stress tensor. The conformal covariance of the operator product expansion in the Thirring model is verified, but the vacuum state is found to be invariant only under theO 2,2 subalgebra of the infinite conformal algebra.

Riassunto

Si costruiscono i generatori infinitesimi dell’algebra conforme in due dimensioni spazio-temporali, algebra che risulta essere ad infiniti generatori, a partire dal tensore energia-impulso della teoria. Si verifica esplicitamente la covarianza conforme dell’espansione operatoriale nel modello di Thirring. Però si trova che lo stato di vuoto è invariante soltanto sotto la sottoalgebraO 2,2 della completa algebra conforme.

Реэюме

Иэ тенэора напряжений конструируются бесконечно малые генераторы бесконечномерной конформной алгебры в двух пространственно-временных иэмерениях. Проверяется конформная ковариантность раэложения проиэведения операторов в модели Тирринга. Однако, обнаружено, что вакуумное состояние является инвариантным только относительно суб’алгебрыO 2, 2 бесконечной конформной алгебры.
