| Outline of Final Research Achievements |
It is well known that the the theory of higher dimensional data compression is closely related to the theory of functions of several variables, because the 13th problem formulated by Hilbert in 1900 pointed out the way of decomposing functions of several variables into some functions of less several variables in the way of keeping reproducible would play important roles in the theory of nomographs, namely, graphs which are used to make numerical calculation without calculators much easier. The first result is to give a negative solution to the infinitely differentiable function version of the Hilbert's 13th problem and the second result is to develop a numerical-integration-oriented higher dimensional data decomposition. which can accelerate Simpson'approximate integration.
