| Research Abstract |
I researched automatic structure which appears in algebras.
(1) Automatic structure of semi-group theory.
There is a rational operation in semi-groups and generation D = J is filled in the equivalent relation of Green. It was able to divide into three types and we could obtain the structure.
(2) Automatic structure of ring theory.
Local cohomology of Weyl algebra can be calculated by using Groebner basis and Torsion theory. We obtained the algorithm to calculate extension of non-commutative valuation ring under some conditions. And another I researched automatic structure of number theory and logic.
