The main question:
Where we can find the KEY
The
Tool
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
=>

We consider the toy models in which
the physical space is a continuous

and THE TIME IS GLOBAL !
Then we have local solutions:
With common frequency:

The basic
Theorem:
Using proper changes of variables we can transform the Z-equation in the
Schrodinger-like form:

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.

looking

the
KEY !
