To the definition of the global transformation in 2-dimensional linear spaces of continuous functions. (English) Zbl 0715.34012

Summary: We study the question relating to the equivalence of definitions of the global transformation in two 2-dimensional linear spaces of continuous functions. We apply the definitions of transformation introduced by O. Borůvka [Lineare Differentialtransformationen 2. Ordnung. Berlin (1967; Zbl 0153.112); Englisch translation: London 1971], F. Neumann [Differ. Equations 19, 571-580 (1983); translation from Differ. Uravn. 19, No.5, 799-808 (1983; Zbl 0524.34044)] and K. Stach [Arch. Math., Brno 3, 117-138 (1967; Zbl 0217.400)], in studying the spaces of solutions of the second-order linear differential equations in the Jacobian form, the spaces of solutions of the nth order homogeneous linear differential equations, the 2-dimensional linear spaces of continuous functions, respectively.
