非紧域函子的自同态代数

On endomorphism algebras of functors with non-compact domain

Brian Day

摘要:

作为[2]和[3]的发展,我们对从合适的幺半范畴范畴C到Vect_k的每个k-线性分裂半群函子构造了Vect_k中的“VN-双代数”.这里的主要目的是避免对定义域范畴C的生成元的习惯紧性假设(参见图1)。[3])。请注意,这里定义的Vect_k中的VN-双代数不一定是通常意义上的k-代数那样的von Neumann正则,前缀“VN-”来自von Neumann正则半群的基于集合的情况。

英文摘要:

As a development of [2] and [3], we construct a "VN-bialgebra" in Vect_k for each k-linear split-semigroupal functor from a suitable monoidal category C to Vect_k. The main aim here is to avoid the customary compactness assumptions on generators of the domain category C (cf. [3]). Please note that the VN-bialgebras in Vect_k defined here are not necessarily von Neumann regular as k-algebras in the usual sense, the prefix "VN-" coming from the Set-based case of von Neumann regular semigroups.
