Challenging routes in quantum cosmology

The aim of this book is to convey a broad perspective of what quantum cosmology is and how it can be a relevant field of research in the 21st century. A series of challenges (or research directions to follow) are provided, in the form of chapters, as the means of forwarding some of the main elements of quantum cosmology. This is therefore a more practical oriented book, where a reasonable amount of technical features are presented in a compact appendix.
