分段遗传Dynkin型代数和推广的Dynkin型代数

Piecewise Hereditary algebras of Dynkin and extended Dynkin type

Eduardo N. Marcos, Marcelo Moreira

摘要:

本文研究了分段遗传的关联代数的描述问题,我们称之为Phia代数。本文在Assem,Nehring和Skowroplowski的基础上,描述了Dynkin型Phia代数的同构关系,并引入了一类新的扩展Dynkin型Phia代数,我们称之为ANS族.在这个描述中,重要的方法是一个平凡的扩展切割集,受此启发,我们提出了一个计算机程序,它显示了确切的切割集上的给定平凡的扩展,结果对关联代数。

英文摘要:

We present a study on the description of incidence algebras that are piecewise hereditary, which we denominate Phia algebras. We describe the quiver with relations of the Phia algebras of Dynkin type and introduce a new family of Phia algebras of extended Dynkin type, which we call ANS family, in reference to Assem, Nehring, and Skowroński. In this description, the important method was the one of cutting sets on trivial extensions, inspired by this we made of a computer program which shows exactly the cutting sets on the given trivial extension that result on incidence algebras.
