چکیده
We describe a mechanism for using discrete symmetries to solve the doublet-triplet splitting problem of four dimensional supersymmetric GUT's. We present two versions of the mechanism, one via " deconstruction, " and one in terms of M-theory compactification to four dimensions on a manifold of G 2 holonomy.

Using two dimensional (2D) N = 4 sigma model, with U(1) gauge symmetry, and introducing the ADE Cartan matrices as gauge matrix charges, we build ” toric” hyperKahler eight real dimensional manifolds X8. Dividing by one toric geometry circle action of X8 manifolds, we present examples describing quotients X7 = X8 U(1) of G2 holonomy. In particular, for the Ar Cartan matrix, the quotient space i...

Noncommutative three-dimensional gravity can be described in terms of a noncommuta-tive Chern-Simons theory. We extend this structure and also propose an action for gravi-tational fields on an even dimensional noncommutative space. The action is worked out in some detail for fields on a noncommutative CP 2 and on S 4 .

The proof of one-loop renormalizability of the general Lorentz-and CPT-violating extension of quantum electrodynamics is described. Application of the renormalization-group method is discussed and implications for theory and experiment are considered.

We discuss a realistic supersymmetric SU(6) grand unified theory with the GUT flat direction being lifted by soft supersymmetry breaking, and the doublet-triplet splitting being achieved with Higgs as a pseudo-Goldstone boson. The theory offers a simple solution to the false vacuum and monopole
