In the years 1952–1953, I had finished my studies at École Normale Supérieure, and I had a position of research in CNRS, under the supervision of Laurent Schwartz. His book on the theory of distributions had been recently published; this book and his paper on mean periodic functions were full of open problems on linear differential equations, especially with constant coefficients and convolution equations. I was mainly interested in the problem of “elementary solutions”: given a differential polynomial P with constant coefficients, does there exist a distribution f on ℝ n verifying Pf=δ, δ the Dirac measure?
