Weakly invertible cells in a weak $ω$-category

Soichiro Fujii, Keisuke Hoshino, Yuki Maehara

AI总结:

本文采用余归纳定义研究Batanin-Leinster弱$ω$-范畴中的弱可逆胞腔,证明其在球状粘贴下封闭,并将严格$ω$-范畴中的基本性质推广至弱$ω$-范畴,进而证明每个弱$ω$-范畴都存在最大的弱$ω$-子群胚。

摘要:

本文研究Batanin-Leinster意义下弱$ω$-范畴中的弱可逆胞腔,采用弱可逆性的余归纳定义。我们证明弱$ω$-范畴中的弱可逆胞腔在球状粘贴运算下封闭。利用这一结果,我们将严格$ω$-范畴中已知成立的弱可逆胞腔的基本性质推广到弱$ω$-范畴,并证明每个弱$ω$-范畴都具有一个最大的弱$ω$-子群胚。

英文摘要:

We study weakly invertible cells in weak $ω$-categories in the sense of Batanin-Leinster, adopting the coinductive definition of weak invertibility. We show that weakly invertible cells in a weak $ω$-category are closed under globular pasting. Using this, we generalise elementary properties of weakly invertible cells known to hold in strict $ω$-categories to weak $ω$-categories, and show that every weak $ω$-category has a largest weak $ω$-subgroupoid.
