Theory for Quantization of Gravity

The unification of Einstein's field equations with Quantum field theory is a problem of theoretical physics. Many models for solving this problem were done, i.e. the String Theory or Loop quantum gravity were introduced to describe gravity with quantum theory. The main problem of this theories is that they are mathematically very complicated. In this research text, there is given another description of gravity unified with Quantum field theory. In this case, gravity is described so that for weak gravitational fields the (semi)classical gravity desciption is equivalent.
