单纯分解的一个比较定理

A comparison theorem for simplicial resolutions

Julia Goedecke, Tim Van der Linden

摘要:

众所周知,巴尔和贝克的共单同调的定义对于系数函子取值于半阿贝尔范畴而不是阿贝尔范畴也是有意义的。问题是这样一个同调论是否具有与阿贝尔情形相同的方便性质。在这里,我们专注于所选择的comonad的独立性:条件的同源依赖于诱导类的投射。

英文摘要:

It is well known that Barr and Beck's definition of comonadic homology makes sense also with a functor of coefficients taking values in a semi-abelian category instead of an abelian one. The question arises whether such a homology theory has the same convenient properties as in the abelian case. Here we focus on independence of the chosen comonad: conditions for homology to depend on the induced class of projectives only.
