Summary
The covariant, unitary and causalS-matrix for nonlocal relativistic quantum field theories is constructed. ThisS-matrix is based on a new notion of the covariant chronological ordering.
Riassunto
Si elabora la matriceS causale, unitaria e covariante per le teorie quantistiche dei campi relativistiche non locali. Questa matriceS è basata su una nuova nozione dell'ordine cronologico covariante.
Резюме
Конструируется ковариантная, унитарная и причиннаяS-матрица для нелокальных релятивистских квантовых полевых теорий. ПредложеннаяS-матрица основана на новом определении ковариантного хронологического упорядочения.
