L'une des activités principales du scientifique explorant le monde est la recherche d'invariants. Les mathématiques n'échappent pas à cette règle systématique: il est toujours conseillé de s'intéresser à "ce qui ne change pas" dans un cadre fixé.
This monograph summarizes the recent major achievements in Möbius invariant QK spaces. First introduced by Hasi Wulan and his collaborators, the theory of QK spaces has developed immensely in the last two decades, and the topics covered in this book will be helpful to graduate s…

"This book contains an in-depth overview of the current state of the recently emerged and rapidly growing theory of Gk/n groups, picture-valued invariants, and braids for arbitrary manifolds. Equivalence relations arising in low-dimensional topology and combinatorial group theor…
"The semantic tradition makes languages and their interpretations the objects of formal study. It has flourished through the development of model theory, initially used by Tarski for the formal explication of the notions of truth and logical consequence. Since the midst of the t…
