The Upper Nilradical Connected with a Right Ideal in the Ring (Z[√3], +,·)

In addition to theoretical investigations of radicals connected with a right ideal in associative rings, we seek to build models implementing the achieved results. In the process, we succeeded in building an upper nilradical connected with a right ideal in the ring (Z[√3], +,·). This is presented in the paper, after some necessary theoretical preliminaries.
