TY - JOUR TI - GEOMETRIZATION OF A GENERAL COLLINEATION AU - TSAMPARLIS, M JO - Journal of Mathematical Physics PY - 1992 VL - 33 TODO - 4 SP - 1472-1479 PB - AMER INST PHYSICS SN - 0022-2488, 1089-7658 TODO - 10.1063/1.529724 TODO - null TODO - Geometrization of a general collineation means to express the collineation as necessary and sufficient conditions on the kinematic quantities (shear, vorticity, expansion) of the congruence of the vector field generating the collineation. It is shown that the generic form of a collineation is L(xi)g(ab) = 2-psi-g(ab) + H(ab) where H(ab) is a traceless symmetric tensor. A general theorem concerning the geometrization of the generic collineation is presented and its applications are discussed. ER -
