right primitive ideal

A two-sided ideal $P$ of an associative ring $R$ (cf. Associative rings and algebras) such that the quotient ring $R/P$ is a (right) primitive ring. Analogously, by using left primitive rings one can define left primitive ideals. The set $\mathfrak P$ of all primitive ideals of a ring, endowed with some topology, is useful in the study of various classes of rings. Usually $\mathfrak P$ is topologized using the following closure relation: $$\mathop{Cl} A = \left\{ { Q \in \mathfrak P : Q \supseteq \cap\{P:P\in A\} } \right\}$$ where $A$ is a subset of $\mathfrak P$. The set of all primitive ideals of a ring endowed with this topology is called the structure space of this ring.
