Abstract: In this paper we study normalizing extension of semiprime rings. For an extension $S$ of $R$ we construct the canonical torsion-free $S^*$, which is a normalizing extension of the symmetric ring of quotients $Q$ of $R$. We extend results which are known for centralizing extensions and for normalizing bimodules to one-to-one correspondence between closed ideals. Finally we study prime ideals, non-singular prime ideals and (right) strongly prime ideals of intermediate extensions.

Classification (MSC2000): 16D20, 16D30, 16S20, 16S90
