All formulas include misprints. In formulas (la) and (lb), all equal signs should be replaced by a multiplication sign (a star), In formulas (2), (3), (4) and (5), all but the first equal signs should be replaced by a multiplication sign. The first parenthesis on the second line of (3) should be reversed. In formula (6), the last upper and lower indexes of R should be (respectively) i 2 m _ 1 i2m and J2m - 1 J2rn, and the following 0 should be 6. COVARIANT (g([i, j], [] ), E([i, j], [] ) + L *(2*H([i, j], [1 ) - E([i, ]], [] )*H([], [] ))) (la)
