This special issue is dedicated to Jean-Pierre Bourguignon on the occasion of his 75th birthday, and contains articles on spin geometry, spectral problems, Ricci and scalar curvatures, Einstein metrics, Kähler–Einstein metrics and other canonical metrics in complex geometry (extremal, etc.), positive curvature, Ricci flow, relativity, geometric analysis, mathematics and society.

The volume consists of 26 papers for a total of 616 pages.

We are grateful to all the authors who contributed to this volume and to the referees for providing constructive reviews.
