幺半群作为超群的对称化
Symmetrization of monoïds as hypergroups
摘要:
我们适应的Grothendieck群的建设相关联的交换monoïd处理幂等monoïd。我们的构造适用于一类有限的交换幺半群,它在许多情况下与Grothendieck群构造一致,并产生一个超群,解决了态射到超群的普遍问题。在幂等幺半群的情况下,给出了期望的非平凡超群构造。
英文摘要:
We adapt the construction of the Grothendieck group associated to a commutative monoïd to handle idempotent monoïds. Our construction works for a restricted class of commutative monoïds, it agrees with the Grothendieck group construction in many cases and yields a hypergroup which solves the universal problem for morphisms to hypergroups. It gives the expected non-trivial hypergroup construction in the case of idempotent monoïds.
