假单胞菌和下降,PhD论文(第1章)
Pseudomonads and Descent, PhD Thesis (Chapter 1)
摘要:
这是我的博士论文的引言部分。本论文由一个介绍性章节和四篇作者在科英布拉大学攻读博士学位期间在Maria Manuel Clementino指导下撰写的论文组成。在第一章中,我们将简要介绍我们的工作范围,并简要描述每篇论文的原始贡献,包括它们之间的一些联系。本文还简要介绍了我们的主要背景--$2$ -维范畴论。在这方面:(1)对“伪Kan扩张与下降”一章中的Beck-Chevalley条件进行了理论上的解释(arXiv:1606.04999),(2)我们应用了“关于双共轭和松弛代数的提升”的结果(arXiv:1607.03087)在单子的形式理论的一个推广的设置和(3)我们应用“关于双伴随三角形”的双伴随三角形定理(aXiv:1606.05009)研究(伪)可指数伪余代数。
英文摘要:
This is the introductory chapter of my PhD Thesis. This thesis consists of one introductory chapter and four single-authored papers written during my PhD studies at the University of Coimbra under supervision of Maria Manuel Clementino. In this first chapter, we give a glance of the scope of our work and briefly describe elements of the original contributions of each paper, including some connections between them. We also give a brief exposition of our main setting, which is $2$-dimensional category theory. In this direction: (1) we give an exposition on the doctrinal adjunction, focusing on the Beck-Chevalley condition as used in Chapter "Pseudo-Kan Extensions and Descent" (arXiv: 1606.04999), (2) we apply the results of "On lifting of biadjoints and lax algebras" (arXiv: 1607.03087) in a generalized setting of the formal theory of monads and (3) we apply the biadjoint triangle theorem of "On biadjoint triangles" (aXiv: 1606.05009) to study (pseudo)exponentiable pseudocoalgebras.
