结合代数的扩张

Extensions of associative algebras

Alice Fialowski, Michael Penkava

摘要:

本文给出了结合代数扩张问题的纯上同调解释,即一个结合代数扩张为另一个结合代数的问题.然后,我们给出了一个类似的解释无限小变形的扩展。特别地,我们考虑了结合代数的表示的无穷小变形。

英文摘要:

In this paper, we give a purely cohomological interpretation of the extension problem for associative algebras; that is the problem of extending an associative algebra by another associative algebra. We then give a similar interpretation of infinitesimal deformations of extensions. In particular, we consider infinitesimal deformations of representations of an associative algebra.
