# Ramanujan prize awarded to Yuguang Shi

The International Centre for Theoretical Physics (ICTP) hosted the 2010 Ramanujan Prize ceremony on 10 May 2011, honouring the work of award recipient Yuguang Shi from the School of Mathematical Sciences, Peking University, China.

The prize recognizes Shi's "outstanding contributions to the geometry of complete (noncompact) Riemannian manifolds, specifically the positivity of quasi-local mass and rigidity of asymptotically hyperbolic manifolds."

It is also an acknowledgement of the substantial contribution that Shi has made to mathematics in China through over 15 years of teaching and research. He said that the level of interest in theoretical fields such as mathematics is growing in China and that he hopes Chinese researchers and ICTP forge stronger ties.

Shi said that ICTP is an excellent platform for researchers from all over the world to come together and share ideas and knowledge. He looks forward to collaborating with ICTP researchers in the future.

Immediately following the award ceremony, Shi gave a presentation on "Some Geometry Problems Related to General Relativity," based on his current research interest in differential geometry and its relation to general relativity.

Shi is the sixth recipient of the Ramanujan Prize, which was established in 2005. It is awarded annually to a young mathematician (under 45) from a developing country.

The prize is funded by the Norwegian Academy of Science and Letters through the Abel Fund, with the cooperation of the International Mathematical Union (IMU).

IMU was represented by Manuel de Leon who spoke during the ceremony, as did ICTP director Fernando Quevedo.

**The Ramanujan Prize selection committee:**

The International Centre for Theoretical Physics (ICTP) awards the prize through a selection committee of five eminent mathematicians appointed in conjunction with the International Mathematical Union (IMU).

### Congratulations to Karen Uhlenbeck from University of Texas at Austin

"At the University of Texas at Austin and the Department of Mathematics, we are delighted and tremendously proud of Karen Uhlenbeck, recipient of the 2019 Abel Prize" - Thomas Chen, Chair of the University of Texas at Austin Math Department

"On behalf of the American Mathematical Society, it is my great pleasure to congratulate Professor Karen Uhlenbeck, recipient of the 2019 Abel Prize. Professor Uhlenbeck has made legendary advances in several fields of mathematics. Her early groundbreaking work on harmonic maps gave rise to a new field, geometric analysis. Her analysis via gauge theory of solutions of Yang-Mills equations, had and will continue to have a profound influence on all future work in this field. She transformed the fields of geometry and analysis, crossing boundaries and making deep discoveries at the interfaces." AMS President Jill Pipher
