The main question:

Where we can find the KEY

The basic problem of the standard

approach to quantum gravity is

caused by the very classical

Einsten-Hilbert action in D = 1 + d :

for dimension D > 2

Then we have local solutions:

CONCLUDING REMARKS

1. A signal, related to degree of freedom specific for the higher-dim

part does not penetrate into the smaller-dim part, because of

centrifugal force at the junction.

2. Our New THEOREM relates the KG problem on variable geometry

to the Schrodinger-type eq with potential, generated by the

variation.

3. The specific spectrum of scalar excitations characterizes the junction

Geometry. This observation suggest an idea:

To explain the observed particles spectra by geometry of the junction

between domains of the space-time with different topological dimension.

4. The parity violation, due to the asymmetry of space geometry could

yield the CP-violation. This, in turn, gives a hope to discover a

simple natural basis for Explanation of the real situation,

concerning C, P, and T properties of the particles.
