Abstract:
We discuss a C(N)D-statement consisting of the known and elaborating in decades C(N)D-1 statement which can be and should be interpreted as quantitative statement of approximation theory and calculus mathematics, which together with new prolongations of C(N)D-2 and -3 in aggregate is suggested as natural theoretical and computational scheme of further developments of numerical analysis.
Keywords:computational (Numerical) Diameter (C(N)D), approximation theory in quantitative statement, calculus mathematics, recovery by exact and inexact information, limiting error, new scheme of numerical analysis.
