Recurrence relations for relativistic two centre matrix elements
A. C. Ilarraza-Lomelí, R. P. Martínez-y-Romero, H. N. Núñez-Yépez +2
Recursion formulae are derived for the calculation of two centre matrix elements of a radial function in relativistic quantum mechanics. The recursions are obtained between not nec…

Singularities and isotropy in a Brans-Dicke Bianchi-type VII universe
H. N. Núñez-Yépez
We study the dynamical effects in the scale factors due to the scalar -field at the early stages of a supposedly anisotropic Universe expansion in connection with the problem of…
