Braverman和Gaitsgory(1996)的结果给出了滤波代数是Koszul代数的poincar<s:1> - birkhoff - witt (PBW)变形的充分必要条件。本文的主要定理建立了等价于Braverman-Gaitsgory定理的条件,以有效地确定二次多项式的PBW变形。特别地,给出了这个结果的图解解释,并讨论了在什么情况下这个定理的一些条件不需要检验。还提供了几个示例。最后,利用这些工具,我们证明了每个二次单项式代数允许一个非平凡的PBW变形。
A result of Braverman and Gaitsgory from 1996 gives necessary and sufficient conditions for a filtered algebra to be a Poincaré-Birkhoff-Witt (PBW) deformation of a Koszul algebra. The main theorem in this paper establishes conditions equivalent to the Braverman-Gaitsgory Theorem to efficiently determine PBW deformations of quadratic monomial algebras. In particular, a graphical interpretation is presented for this result, and we discuss circumstances under which some of the conditions of this theorem need not be checked. Several examples are also provided. Finally, with these tools, we show that each quadratic monomial algebra admits a nontrivial PBW deformation.
