# Philibert Nang from Gabon wins the 2011 Ramanujan Prize

Professor Philibert Nang (44), École Normale Supérieure, Laboratoire de Recherche en Mathématiques, Libreville, Gabon, has been named the winner of the 2011 Ramanujan Prize for Young Mathematicians from Developing Countries. Philibert Nang will receive the prize at an award ceremony at Tata Institute in Mumbai, India on the 23rd of February.

The Ramanujan Prize is awarded jointly by the Abdus Salam International Centre for Theoretical Physics, the Niels Henrik Abel Memorial Fund, and the International Mathematical Union.

The Prize is in recognition of Professor Philibert Nang's outstanding contributions to the algebraic theory of D-modules. He has important classification theorems for equivariant algebraic D-modules, in terms of explicit algebraic invariants, and his results complement the insights obtained by others using perverse sheaves, and thus shedding new light on the Riemann-Hilbert correspondence.

The Prize is also in recognition of Dr. Nang's determined pursuit of high level research while engaged in an academic career in his home country of Gabon, Africa. It is hoped that his example will inspire other young African mathematicians working at the highest levels while based in Africa.

The Prize is awarded annually to a researcher from a developing country less than 45 years of age on 31 December of the year of the award, who has conducted outstanding research in a developing country. Researchers working in any branch of the mathematical sciences are eligible.

The Ramanujan Prize was awarded for the first time in 2005.

The Ramanujan Prize is supported financially by the Norwegian Niels Henrik Abel Memorial Fund. The Ramanujan Prize carries a $15,000 cash award.

"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
