The covariant and contravariant components [g.sub.ij] and [g.sup.ij] of the metric tensor of [mathematical expression not reproducible], the Christoffel symbols [mathematical expression not reproducible] are then defined as follows (the explicit dependence on the variable x [member of] [bar.[OMEGA]] is henceforth dropped):
Then, the covariant components of Riemann tensors on [??]([[bar.[OMEGA].sup.[epsilon]]) are defined by
Hence, the covariant and contravariant components of the metric tensor on S are given by
A 2 (gender) x 11 (subtest) MANCOVA was performed, group as a covariant, and revealed a gender effect [R(11,159) = 2.43; p < .01].
A 6 (age) x 11 (subtest) MANCOVA was performed, group as a covariant, and revealed an age effect [R (55,721) = 5.47; p < .001].

Exhibit 4 establishes that simple product-moment correlations isolate a consistent set of covariants in this first cluster of variables.
Findings from exhibits 4 and 5 show, at two levels of abstraction, that LC covariants seem consistent in eleven Chicago metro governments.
The interface between the political and administrative sectors--between the board and the staff headed by a CAO--is often tense, and exhibit 6 provides support for the hypothesis that LC has attractive covariants in this often troublesome linkage.
