Theorem 35 sets up covariant identities for generalized functionals of Z.
Our first step towards a covariant canonical quantization begins with defining a quantized space-time and its quanta.

The corresponding Euler-Lagrange's equation and energy - momentum tensors are found on the basis of the covariant Noether's identities.
Let us remark that the class of almost complex and almost product connections in vector bundles endowed with such endomorphisms are discussed also in [19] but our study follows a different path: we unify the treatment of these geometries and in this way we firstly determine the mean covariant derivative from an arbitrary pair ([nabla], [[nabla].sup.[lambda]]) and secondly we derive the set C([lambda]).
For clearer, the interval estimations of the scale parameter [eta] and MTBF under each working condition covariant level are shown in Figures 1 and 2.
where i = [square root of -1] is the imaginary unit, m [greater than or equal to] 0 is the rest mass, [PHI] = [PHI](x, t) = ([[phi].sub.1](x, t), [[phi].sub.2](x, t))([dagger]), ([dagger]) is the transpose, [[phi].sub.1] and [[phi].sub.2] are complex-valued functions, [bar.[PHI]] := [[PHI].sup.*][[gamma].sup.0] represents the adjoint spinor, the superscript * denotes the conjugate transpose, [L.sub.1] [[PHI]] stands for the self-interaction Lagrangian, [[partial derivative].sub.[mu]] represents the covariant derivative ([[partial derivative].sub.0] = [[partial derivative].sub.t], [[partial derivative].sub.1] = [[partial derivative].sub.x]), and [[gamma].sup.[mu]] denotes the Dirac matrices ([mu] = 0,1); that is,
