Causality in indefinite metric theories

Причинность в теориях с индефинитной метрикой

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

Summary

It has recently been claimed by Rechenberg and Sudarshan that theories with shadow states are consistent with macroscopic causality, even though they lack the normal physical-region analytic structure. This claim is based on a number of incorrect statements, which are here pointed out. These errors invalidate the claim.

Riassunto

Si è recentemente asserito da parte di Rechenberg e Sudarshan che le teorie con stati ombra sono compatibili con la causalità macroscopica, benchè manchino della normale struttura analitica della regione fisica. Questa asserzione è fondata su una quantità di affermazioni incorrette, che qui si puntualizzano. Questi errori inficiano la validità dell’asserzione.

Реэюме

Недавно Реченберг и Сударщан выскаэали утверждение, что теории с теневыми состояниями не согласуются с макроскопической причинностью, даже если они не имеют нормальной аналитической структуры в фиэической области. Это утверждение основывается на ряде некорректных формулировок, которые отмечаются в настояшей работе. Эти некорректные формулировки делают недействительным укаэанное утверждение.
