String formalism in superspace-time (Q2637070)

The author uses the super-space approach from quantum cosmology and string theory to simplify known calculations in quantum field theory of curved space-time. Note: See also the paper [Russ. Phys. J. 53, No. 1, 1--8 (2010); translation from Izv. Vyssh. Uchebn. Zaved., Fiz. 2010, No. 1, 3--9 (2010; Zbl 1205.81119)] by the same author about the same topic. Remark: The quality of the translation is generally good, but the following misleading translation should be observed: Usually, quantum states with negative norm are called ghosts, in the present paper they are called spirits.
