Abstract

We investigate the total CR twist functional on transversal curves in the standard CR 3-sphere S^3 in C^2. The question of the integration by quadratures of the critical curves and the problem of existence and properties of closed critical curves are addressed. A procedure for the explicit integration of general critical curves is provided and a characterization of closed curves within a speci c class of general critical curves is given. Experimental evidence of the existence of in nite countably many closed critical curves is provided.
