高阶关系双模

The higher relation bimodule

Ibrahim Assem, M. Andrea Gatica, Ralf Schiffler

摘要:

给定一个整体维数有限的有限维代数A,我们考虑A的平凡扩张由A-A-双模$\oplus_{i\ge 2} \Ext^2_A(DA,A)$构成,我们称之为高关系双模.我们首先给出了一个配方,允许构建这个平凡的扩展的情况下,A是一个字符串代数,然后应用它来证明,如果A是温柔的,那么高关系双模的张量代数是温柔的。

英文摘要:

Given a finite dimensional algebra A of finite global dimension, we consider the trivial extension of A by the A-A-bimodule $\oplus_{i\ge 2} \Ext^2_A(DA,A)$, which we call the higher relation bimodule. We first give a recipe allowing to construct the quiver of this trivial extension in case A is a string algebra and then apply it to prove that, if A is gentle, then the tensor algebra of the higher relation bimodule is gentle.
