✦ Synopsis

The motive for the introduction of a fictitious field and the vacuum in thermo field dynamics is derived from Euclidean path integrals. We show that the occurrence of a fictitious system, both in the theory of Umezawa and Takahashi at finite temperature and the one of Israel for black hole backgrounds, can be related to the geometry of the Euclidean section of their spacetime.

Abs~act-"Path-independent" integrals are presented for use in fracture dynamics. One class of integrals is based on a reciprocal theorem and the other is related to the energy flow into a moving crack tip. These integrals may be used to numerically calculate the dynamic stress intensity factor in el
