It is shown that an element a in a ring is Drazin invertible if and only if so is an; the Drazin inverse of a is given by that of a(n), and vice versa......

Let M-3 be a three-dimensional almost co-Kahler manifold whose Reeb vector field is harmonic. We obtain some local classification results of M-3 under......
