| Outline of Final Research Achievements |
For the renormalization from the invariant-theoretic point of view, we studied some basic facts on the Capelli identities, Bell polynomials and differential operator of infinite variables, and universal enveloping algebras.These are necessary for the study of the infinite dimensional group of general coordinate transformation, and for its invariants. Their importance is that they are related both group theoretic and combinatorial points of view. In particular, the study on the Bell polynomials using the differential operators of infinite variables are similar to classical invariant theoy in the sense of the featuring "ground form". This will be useful in the calculation of non-commuting variables like in the universal enveloping algebras.
