Main Article Content

Abstract

In this paper, we first state the prolongation problem of ring extensions and show that its data (the triple ) determines a regular E-system. Each extension of this regular E-system is a prolongation of the extension E. Next, we prove the result on the classification of extensions of regular E-systems. Then, we obtain the result on the prolongation problem of a ring extension.
