Giovanni Calvaruso is Professore Associato at the Università del Salento. His research is in pseudo-Riemannian Geometry, with a particular focus on homogeneity questions.Marco Castrillón López is Profesor Titular de Universidad at the Universidad Complutense de Madrid. His research is at the interface between Differential Geometry and Theoretical Physics, mainly in the context of Classical Field Theories.

“There are several reasons to read this book. One is to have a modern point of view for the study of homogeneous structures with a special attention on holonomy. Both classical and recent results are presented and this aspect will lead the reader to a better perception of these notions. Another reason to have this book on the reading list is that it is self-contained and describes the notions to everybody having a basic knowledge of smooth manifolds, Lie groups and theory of representations.” (Marian Ioan Munteanu, zbMATH 1437.53002, 2020)
