We consider a relativistic frame of reference, generalized in the polar sense [1]–[2],and the adapted non-holonomic techniques;then, we extend to non-orthogonal case second order propertiesof a standard frame of reference: Riemann tensor decomposition, Lie derivatives of the Ricci rotation coefficients, commutation formulae and spatial Bianchi identity. 相似文献

Summary From an integral rapresentation of theHankel functions H v (1) (v) and H v (2) (v) and by usingvan der Corput's theory of enveloping series we obtain an asymptotic expansion forBessel functions Jv(v) and Yv(v). An upper bound for the error term is also obtained.相似文献
