An isomorphism problem for algebras defined by some quivers and nonadmissible ideals

Stanisław Kasjan, Maja Sędłak (2008)

Colloquium Mathematicae

Similarity:

Given a quiver Q, a field K and two (not necessarily admissible) ideals I, I' in the path algebra KQ, we study the problem when the factor algebras KQ/I and KQ/I' of KQ are isomorphic. Sufficient conditions are given in case Q is a tree extension of a cycle.

A characterization of Q-algebras of type F

W. Żelazko (2004)

Studia Mathematica

Similarity:

We prove that a real or complex unital F-algebra is a Q-algebra if and only if all its maximal one-sided ideals are closed.
