DIMENSIONAL REUCTIONin (1+2)-dimensionalCYLINDRICAL UNIVERSESandKLEIN-GORDON WAVESP. P. Fiziev,D.V. ShirkovBLThPh, JINR, DubnaTalk at the MI RAS SeimarMoscow , April 20, 2011

The basic problem of the standardapproach to quantum gravity is causedby the very classicalEinsten-Hilbert action in D = 1 + d :for dimension D > 2A New Idea:D. V. Sh., Particles and Nuclei (PEPAN), Lett. No 6 (162), 2010

Examples of 2-dim manifolds with variable geometries(surface of bottles)

Relation of the above (relativistic) examples withthe modern solid state physics of two-dimensional crystalsgraphene, fulerene,carbon nanotubes,carbon nanobuds,etc:

CONCLUDING REMARKS1. A signal, related to degree of freedom specificfor the higher-dim part does not penetrateinto the smaller-dim part,centrifugal force at the junction2. The specific spectrum of scalarexcitations characterizes the junctiongeometry. A new idea: To explain thebecause ofobserved particles spectra by geometry of thejunction between domains of the space-timewith different topological dimension.

5. The parity violation, due to the asymmetryof space geometry could yield the CP- and T-violation.This gives a hope to discover a simple natural basis forexplanation of the real situation, concerningC, P, and T properties of the particles.6. Barion-antibarion asymmetry versusasymmetry of the space-time ???7. The Big Bang = ? = time transformation ofspace dimensions ???
