On phases of accompanying spaces to a linear two-dimensional space of functions with a continuous first derivative. (English) Zbl 0551.34003

This paper deals with relations between phases of two accompanying spaces \(P_{\rho}[\alpha,\beta]\) and \(P_{\sigma}[\gamma,\delta]\) to the space \(S\subset C_ 1(i)\) from the point of view of Borůvka’s theory on transformations of integrals of the second order differential equations [O. Borůvka, Lineare Differentialtransformationen 2. Ordnung (1967; Zbl 0153.112)].
