Abstract: | We consider approximate relations in the form of a system of linear algebraic equations that yield B
φ
-splines. We construct Lagrange type splines of the first order and give examples of polynomial, trigonometric, hyperbolic,
and exponential B
φ
-splines. We also construct a system of linear functionals biorthogonal to the B
φ
-splines and resolve an interpolation problem generated by this system. For refined nonuniform grids we establish an embedding
of spaces of B
φ
-splines. The decomposition and reconstruction formulas are obtained. Bibliography: 20 titles.
