任意环上Steinberg和Leavitt路代数中理想的分类

A classification of ideals in Steinberg and Leavitt path algebras over arbitrary rings

Simon W. Rigby, Thibaud van den Hove

摘要:

给出了Hausdorff充分广群$G$的Steinberg代数中的理想与$G$中各向同性群的群代数中的某些理想族之间的一一对应.这推广了已知的Steinberg代数的强有效群胚的理想对应定理。我们利用这一点给出了任意交换环上Leavitt路代数理想格的一个完全图描述,推广了域上Leavitt路代数理想的分类。

英文摘要:

We give a one-to-one correspondence between ideals in the Steinberg algebra of a Hausdorff ample groupoid $G$, and certain families of ideals in the group algebras of isotropy groups in $G$. This generalises a known ideal correspondence theorem for Steinberg algebras of strongly effective groupoids. We use this to give a complete graph-theoretic description of the ideal lattice of Leavitt path algebras over arbitrary commutative rings, generalising the classification of ideals in Leavitt path algebras over fields.
