Editors Preface
This book is addressed to a new generation of students and researchers in algebra, topology and category theory who are willing to learn the fundamental notions and principles of some of the active research fields in these areas.
The content of each of the seven chapters of this book fully covers the corresponding specialized course that was taught at the international Summer Schools in Algebra and Topology. The schools were hosted by the Institut de Recherche en Mathmatique et Physique (IRMP) of the Universit catholique de Louvain (UCLouvain) in September 2018 and 2019.
These events were organized in the framework of a project Fonds dAppui lInternationalisation of the Universit catholique de Louvain together with the universities of Coimbra, Padova and Poitiers, aiming at strengthening the research collaborations in mathematics among institutions of the Coimbra Group. The speakers of the summer schools gave some introductory courses on various topics of interest related to their own research fields, addressed to an audience including both masters and PhD students and more experienced mathematicians who were interested in these subjects. The participants in the summer schools came from many different countries in Europe, North America and Asia.
These summer schools greatly facilitated scientific discussions leading to the development of new connections among the various concepts and theories presented during the lectures.
The main subjects in algebra and topology the reader will be introduced to in this volume are:
the theory of comodules and contramodules;
the theory of topological semi-abelian algebras;
the theories of commutative monoids and of non-commutative rings;
regular categories and the calculus of relations;
the categorical approach to commutator theory;
locale theory and the point-free perspective on topology;
the theory of non-associative algebras.
We are very grateful to the many colleagues who have contributed in making this project possible and successful. In particular, we would like to express our gratitude to
Ms. Dana Samson, Prorectrice linternational de lUCLouvain;
Ms. Ana Fernandez-Gacio, Coordinator of the international relations of the Science and Technology Sector of the UCLouvain;
Ms. Anne Querinjean, director of the Muse universitaire de Louvain;
Ms. Carine Baras, Secrtaire de recherche;
Ms. Martine Furnemont, Secrtaire of the IRMP;

Preface to the Book Series Coimbra Mathematical Texts
This new Springer series Coimbra Mathematical Texts is a direct successor of a collection entitled Textos de Matemtica, published by the University of Coimbra, which started in 1993.
The aim of that collection was the publication of advanced mathematics texts resulting from events held at the University of CoimbraMathematics Department, and included conference proceedings as well as monographs related to graduate-level short courses. The first volume in the collection was Classical Invariants, by J. A. Green (1993), and the last one, no. 48, was 13th Young Researchers Workshop on Geometry, Mechanics and Control: three mini-courses (2019). The complete list of volumes, covering a wide range of mathematical topics, may be found at
