The Classification Problem of Finite Rings by Computable Means.
Abstract
This thesis establishes a constructive method for testing when two given finite rings are isomorphic. Currently published theory has classified a significant number of finite rings; however, idealized representatives are almost always used, with no provision for determining which isomorphism class an arbitrary ring belongs. The new results are as follows: 1) Two rings are isomorphic if and only if a specific system of quadratic equations is satisfied. 2) As a corollary, there exists a system of linear equations that positively identify whether or not a ring R possesses a 1. The system also shows how to change a ring's basis so that 1 becomes a basis element. Some tests for existence of other idempotents besides 1 are shown. 3) Some old and new results in classifying finite rings of small rank are obtained.
