This special issue is dedicated to Jean-Pierre Bourguignon on the occasion of his 75th birthday.

Topics for this special issue will include:

• 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.

There is no limit to the length of an article. Deadline for paper submission is June 30, 2023.

How to Submit an Article to the Issue.

All articles will go through the standard peer reviewing procedure of SIGMA.
