“…The minimal possible error (17) in the estimation of the field results from optimization of the process. The same conclusion can be drawn [3] if the observation of the measuring charge is considered with the help of the restricted-path-integral method.…”

The problem of the measurability of the electromagnetic field is investigated 1) in the framework of the abstract restricted-path-integral method, and 2) by explicitly accounting the action of the field onto the meter and its back reaction. The meaning of the previously obtained results as well as of the classical results of Bohr and Rosenfeld are made clear. The restricted-path-integral method with integration over field configurations is shown to give an estimation on the measurability of the field by any device not disturbing the measured field (in the process of measurement) more than by the measurement error. Such method of measurement is necessary for the control of the field in electronic devices.

“…18 Since the quanta of the h µν fields are gravitons, it is inferred from the above considerations that the quantum representation is an approximate one which is valid only when low frequency gravitational phenomena are involved. The conclusion reached on this basis is that the production of field quanta by covariant quantization does not correspond to any real, physical process.…”

“…But we do not explicitly write down these equations because for the derivation of composite particle dynamics the functional states (6) are not the appropriate starting point. In order to relate the original field theory of the spinorfield to composite particle dynamics it is necessary to remove vacuum expectation values from (6), as otherwise a composite particle interpretation of functional states would be impossible.…”

“…where we have restored the time parameter t. We now multiply (101) from the left with e lkr x(k, h, t,j) 6 (J ' and sum over k, h, t. By means of the completeness relation for superspinors we obtain in this case for (101) the result . (104) Equation (104) is the functional formulation and description of a Dirac field coupled to anholonomic connections.…”
