The Theory of Prime Ideals of Leavitt Path Algebras over Arbitrary Graphs

Rangaswamy, Kulumani M.

Original · EN

Given an arbitrary graph E and a field K, the prime ideals as well as the primitive ideals of the Leavitt path algebra Lₖ(E) are completely described in terms of their generators. The stratification of the prime spectrum of Lₖ(E) is indicated with information on its individual stratum. Necessary and sufficient conditions are given on the graph E under which every prime ideal of Lₖ(E) is primitive. Leavitt path algebras of Krull dimension zero are characterized and those with various prescribed Krull dimension are constructed. The minimal prime ideals of Lₖ(E) are are described in terms of the graphical properties of E and using this, complete descriptions of the height one as well as the co-height one prime ideals of Lₖ(E) are given.
