General framework

This introductory chapter briefly presents some of the main notions that appear in the subsequent chapters of this book. We recap a few definitions and results from combinatorics on groups and words, formal language theory, morphic words, k-automatic and k-regular sequences, and dynamical systems. Our aim is not to be exhaustive. The reader can consult this chapter when studying other parts of this book. © Springer International Publishing AG, part of Springer Nature 2018.
