Carbone and R. De Arcangelis, 191{211, Gakkotosho, Tokyo, 2003". On Homogenization and Γ-convergence Luc TARTAR1 In memory of Ennio DE GIORGI When in the Fall of 1976 I had chosen \Homog´en´eisationdans les ´equationsaux d´eriv´eespartielles" (Homogenization in partial differential equations) for the title of my Peccot lectures, which I gave in the beginning of 1977 at Coll`egede France in Paris, I did not know of the term Γ-convergence, which I first heard almost a year after, in a talk that Ennio DE GIORGI gave in the seminar that Jacques-Louis LIONS was organizing at Coll`egede France on Friday afternoons. I had not found the definition of Γ-convergence really new, as it was quite similar to questions that were already discussed in control theory under the name of relaxation (which was a more general question than what most people mean by that term now), and it was the convergence in the sense of Umberto MOSCO [Mos] but without the restriction to convex functionals, and it was the natural nonlinear analog of a result concerning G-convergence that Ennio DE GIORGI had obtained with Sergio SPAGNOLO [DG&Spa]; however, Ennio DE GIORGI's talk contained a quite interesting example, for which he referred to Luciano MODICA (and Stefano MORTOLA) [Mod&Mor], where functionals involving surface integrals appeared as Γ-limits of functionals involving volume integrals, and I thought that it was the interesting part of the concept, so I had found it similar to previous questions but I had felt that the point of view was slightly different.

PROGRESS THE PROGRESS of Negroes in the United States is so great that history will point out what you have done as one of the achievements which mark this age. Your rise is one of the best proofs of the value of the American theory of government. Successes by individuals here and there have been multiplied until now yours is a mass movement. You are advancing all along the line, a sound basis for your having confidence in the future. The world’s work needs every man. I look to see the Negro, prepared by difficulty, and tested by adversity, be a valued factor in upbuilding the commonwealth. In the Middle West, where The Kansas City Call is published, lies opportunity. In addition to urban pursuits you have available for the man of small means, the farm which is one of the primary industries. The Negro in your section can develop in a well rounded way. Above all things, take counsel of what you are doing, rather than of the trials you are undergoing. Look up and go up! Julius Rosenwald [page 2] “PROGRESS EDITION” CELEBRATING THE KANSAS CITY CALL’S TENTH ANNIVERSARY Kansas City, Missouri, Friday, July YOU ARE WELCOME! The changes in The Kansas City Call’s printing plant are completed. We now occupy 1715 E. 18th street as an office; next door at 1717 is our press room and stereotyping room; upstairs is our composing room; in the basement we store paper direct from the mill.

  • Leray in Oflag XVIIA: the Origins of Sheaf Theory

    Leray in Oflag XVIIA: the Origins of Sheaf Theory

    Leray in Oflag XVIIA: The origins of sheaf theory, sheaf cohomology, and spectral sequences Haynes Miller∗ February 23, 2000 Jean Leray (November 7, 1906{November 10, 1998) was confined to an officers’ prison camp (“Oflag”) in Austria for the whole of World War II. There he took up algebraic topology, and the result was a spectacular flowering of highly original ideas, ideas which have, through the usual metamorphism of history, shaped the course of mathematics in the sixty years since then. Today we would divide his discoveries into three parts: sheaves, sheaf cohomology, and spectral sequences. For the most part these ideas became known only after the war ended, and fully five more years passed before they became widely understood. They now stand at the very heart of much of modern mathematics. I will try to describe them, how Leray may have come to them, and the reception they received. 1 Prewar work Leray's first published work, in 1931, was in fluid dynamics; he proved the basic existence and uniqueness results for the Navier-Stokes equations. Roger Temam [74] has expressed the view that no further significant rigorous work on Navier-Stokes equations was done until that of E. Hopf in 1951. The use of Picard's method for proving existence of solutions of differential equa- tions led Leray to his work in topology with the Polish mathematician Juliusz Schauder. Schauder had recently proven versions valid in Banach spaces of two theorems proven for finite complexes by L. E. J. Brouwer: the fixed point theorem and the theorem of invariance of domain.

The article is dedicated to recalling the life and mathematics of Louis Nirenberg, a distinguished Canadian mathematician who recently died in New York, where he lived. An emblematic figure of analysis and partial differential equations in the last century, he was awarded the Abel Prize in 2015. From his watchtower at the Courant Institute in New York, he was for many years a global teacher and master. He was a good friend of Spain. arXiv:2105.10149v2 [math.HO] 27 May 2021 One of the wonders of mathematics is you go somewhere in the world and you meet other mathematicians, and it is like one big family. This large family is a wonderful joy.1 1. Introduction This article is dedicated to remembering the life and work of the prestigious Canadian mathematician Louis Nirenberg, born in Hamilton, Ontario, in 1925, who died in New York on January 26, 2020, at the age of 94. Professor for much of his life at the mythical Courant Institute of New York University, he was considered one of the best mathematical analysts of the 20th century, a specialist in the analysis of partial differential equations (PDEs for short). 1From an interview with Louis Nirenberg appeared in Notices of the AMS, 2002, [43] 2 Louis Nirenberg When the news of his death was received, it was a very sad moment for many mathematicians, but it was also the opportunity of reviewing an exemplary life and underlining some of its landmarks.
