Entropy quantities are connected with the 'degree of compactness' of compact or precompact spaces, and so are appropriate tools for investigating linear and compact operators between Banach spaces. The main intention of this Tract is to study the relations between compactness and other analytical properties, e.g. approximability and eigenvalue sequences, of such operators. The authors present many generalized results, some of which have not appeared in the literature before. In the final chapter, the authors demonstrate that, to a certain extent, the geometry of Banach spaces can also be...

Rapid and transformational actions are ever more urgently needed to achieve a just, resilient, and ecologically sustainable global society, as envisioned and supported by the Sustainable Development Goals. Moreover, dynamic governance approaches are vital for addressing changing and uncertain conditions. At many levels, governance needs to be responsive and flexible - in one word - adaptive. This book provides a state-of-the-art review of the conceptual development of adaptiveness as a key concept in the environmental governance literature, complemented by applications from global, regional,...
