Completely idempotent pseudoconnections on semi-Riemannian and pseudo-Riemannian spaces and concircular fields (Q1405707)

The author continues his study of the theory of pseudoconnections. In Section 1, he recalls some facts of the theory of completely idempotent pseudoconnections. In Section 2, he applies the developed apparatus to construct a canonical connection on a pseudo-Riemannian almost product space and shows how to present Naveira's classification [see \textit{A. M. Naveira}, Rend. Mat. Appl., VII. Ser. 3, 577--592 (1983; Zbl 0538.53045)] in terms of this connection. In Sections 3 and 4, he studies special classes of concircular fields on a semi-Riemannian manifold (i.e., a manifold endowed with a degenerate metric).
