Louis Nirenberg, a renowned mathematician, passed away at the age of 94, marking the end of a significant era in the field of analysis and partial differential equations (PDE). His contributions included the development of the moving planes argument with Gidas and Ni, which established symmetry in ground states, and the interpolation inequality with Gagliardo that extends the Sobolev inequality. Nirenberg also co-created the John-Nirenberg inequality with Fritz John, further solidifying his impact on mathematical analysis. His work has been widely recognized and discussed in various academic circles, including a tribute by Prof. Terrence Tao, who highlighted Nirenberg's profound influence on the field. For more information, a brief biography is available on Wikipedia.

I was sad to learn a few minutes ago of the ending a few days ago of Louis Nirenberg's long life of great achievement.

From Prof. Terrence Tao's site:
Professor Terrence Tao said:
I just heard the news that https://www.abelprize.no/nyheter/vis.html?tid=75971 died a few days ago, aged 94. Nirenberg made a vast number of contributions to analysis and PDE (and his work has come up repeatedly on my own blog); I wrote about his beautiful moving planes argument with Gidas and Ni to establish symmetry of ground states in this post on the occasion of him receiving the Chern medal, and on how his extremely useful interpolation inequality with Gagliardo (generalising a previous inequality of Ladyzhenskaya) can be viewed as an amplification of the usual Sobolev inequality in this post. Another fundamentally useful inequality of Nirenberg is the John-Nirenberg inequality established with Fritz John . . .
Prof Tao continues his reminiscences about the great man here . . .
