The DLF theory can be understood as an attempt to modify the Standard Model by flexing the Poincare symmetry to certain 7-dimensional symmetries. The D part of the theory is known as Segal’s Chronometry which is based on compact cosmos D=U(2) with the SU(2,2) fractional linear action on it. The oscillator group is viewed as a subgroup LG of the conformal group G=SU(2,2) and certain LG-orbits L in D are studied. We prove existence of such L and of such an embedding of F=U(1,1) into D, that D differs from F by a certain torus whereas D differs from L by a circle on that torus. In the general U(p,q) vs U(p+q) case, the Sviderskiy formula is described - as a tribute to the late Oleg S. Sviderskiy (July 31 1969 – March 30 2011).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
