关于多项式函子的扩张

On Extensions of Polynomial Functors

Qimh Richey Xantcha

摘要:

基于投射分解,建立了一个计算多项式函子(主要是整数)扩张的公式。样本计算进行,其中,特别是,表现出一个令人惊讶的非平凡的扩展划分立方体对称立方体。对后者给出了明确的描述。

英文摘要:

A formula for calculating Extensions of (mainly integral) Polynomial Functors is established, based upon projective resolutions. Sample computations are performed, which, in particular, exhibit a surprising non-trivial extension of Divided Cubes by Symmetric Cubes. An explicit description of the latter is given.
