Унитарная граница для эволюции нестационарных состояний

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

Summary

A version of an equation derived by Ersak is studied to obtain rigorous bounds on the rate of change of the integrity of a normalized state.

Riassunto

Si studia una versione di un'equazione dedotta da Ersak per ottenere limiti rigorosi al rapporto di variazione dell'integrità di uno stato normalizzato.

Резюме

Исследуется вариант уравнения, выведенного Эрзаком, для получения строгих границ для интенсивности изменения целостности нормированного состояния.
