与有向图相关的代数的同构

Isomorphisms of algebras associated with directed graphs

Elias Katsoulis, David Kribs

摘要:

本文证明了该图构成图的张量代数的巴拿赫代数同构的完全不变量。对于张量代数与可数有向图没有汇的图形形式的代数同构以及不变。该图也形成了自由半群代数的w*-双连续同构的完全不变量。对于与可数有向局部有限无汇图相关联的自由半群代数,该图也形成代数同构的不变量。

英文摘要:

In this paper we verify that the graph forms a complete invariant for Banach algebra isomorphisms of tensor algebras of graphs. For tensor algebras associated with countable directed graphs having no sinks the graph forms an invariant for algebraic isomorphisms as well. The graph also forms a complete invariant for w*-bicontinuous isomorphisms of free semigroupoid algebras. For free semigroupoid algebras associated with countable directed locally finite graphs with no sinks, the graph also forms an invariant for algebraic isomorphisms.
