Abstract:The Grassmann variables are used to transform a system with constraints into an unconstraint system. As a result, the Schrödinger equation arises instead of the Wheeler-DeWitt one. Formally, the Schrödinger equation describes a system’s evolution, but a definition of the scalar product is needed to calculate the mean values of the operators. We suggest an explicit formula for the scalar product. The calculation of the mean values is compared with the etalon method, in which a redund… Show more
