摘要: A generalized method of dimensional reduction, applicable to theories in curved space, is described. As previous works by other authors, the extra dimensions are related manifold a Lie group. The new feature this work define and study class groups, called “flat groups”, for which resulting theory has no cosmological constant, well-behaved potential, number arbitrary mass parameters. In particular, when analysis applied reduction 11-dimensional supergravity four it becomes possible incorporate three parameters N = 8 theory. This shows that extended supersymmetry allow more possibilities spontaneous symmetry breaking than was previously believed be case.
