# Yoshihiko Matsumoto

Interested in mathematics, especially in differential geometry and function theory of several complex variables. My recent work centers around asymptotically symmetric spaces and their conformal infinities.

## News

• Jan. 16, 2018: Taiji Marugame kindly pointed out some misprints and computational errors in my thesis. (They are all minor, and the main content of the thesis needs no modification.)
• Jan. 16, 2018: We organized the workshop “Geometric Analysis in Geometry and Topology 2017” on December 19–22 last year (my “Foundations and developments of Poincaré-Einstein metrics” was a part of it). The notes offered by the lecturers are made public here.
• Jan. 9, 2018: The notes prepared for the lecture “Foundations and developments of Poincaré-Einstein metrics”, which I gave in December last year in Tokyo, is now available.
• Sep. 1, 2017: I arrived at Stanford University as a two-year visitor.
• Nov. 15, 2016: The paper “Variation of total Q-prime curvature on CR manifolds” is accepted by Advances in Mathematics for publication.
• Oct. 28, 2016: I'll be visiting Stanford University for two years, starting from September next year. Great thanks to the people concerned, especially to the math department members of Osaka University.
• Aug. 10, 2016: The slides and related information (in Japanese) for the public lecture “Geometry of the Hyperbolic Plane” have been uploaded.
