ON A THEOREM OF HORMANDER A. M. Gabrielov In his paper at the Tokiiskoi conference of 1969, L. Hormander proved that for an arbitrary differen- tial polynomial P(D) in R n there exists a fundamental solution having a singularity in some cone K*(P) (defined in paragraph 1). Lars V. Hörmander, in full Lars Valter Hörmander, (born January 24, 1931, Mjällby, Sweden—died November 25, 2012, Lund), Swedish mathematician who was awarded the Fields Medal in 1962 for his work on partial differential equations. Between 1987 and 1990 he served as a vice president of the International Mathematical Union. In mathematics, Hörmander's condition is a property of vector fields that, if satisfied, has many useful consequences in the theory of partial and stochastic differential equations. The condition is named after the Swedish mathematician Lars Hörmander. Biography Lars Hörmander 's father Armand Per Hilding Jönsson (1893 - 1981) was a school teacher in the small fishing village on the south coast of Sweden where Lars was born.

The aim of this book is to give a systematic study of questions con­ cerning existence, uniqueness and regularity of solutions of linear partial differential equations and boundary problems. Let us note explicitly that this program does not contain such topics as eigenfunction expan­ sions,

A TRIBUTE TO LARS HORMANDER 3¨ inequality and much of our knowledge is, in fact, essentially contained in such inequalities. L. Ehrenpreis [32] and B. Malgrange [93] had proven a general theorem on the existence of a fundamental solution for any constant coefficients PDE, and the work

They constitute the most complete and up-to-date account of this subject, by the author who has dominated it and made the most significant contributions in the last decades..It is a superb book, which must be present in every mathematical library, and an indispensable tool for Biography Lars Hörmander 's father Armand Per Hilding Jönsson (1893 - 1981) was a school teacher in the small fishing village on the south coast of Sweden where Lars was born.

Hormander operators. Let us consider in R N +1 the 2nd order linear operator L = m X j =1 X j + X 0 @ t: The X j ’s are smooth vector elds in R N.Let Y:= X 0 @ t and L 0 = P m j =1 X j + X 0. We assume: (H1)With respect to a suitable dilation group, X 1;:::;X m are homogeneous of degree one, whereas Y is homogeneous of degree two. (H2)Every

in 1955 at Hörmander, vars far hette Jönsson, blev filosofie magister 1950, filosofie licentiat 1951 och disputerade 1955 för filosofie doktorsgraden i Lund. Han var elev till de framstående matematikerna Marcel Riesz och Lars Gårding. This book presents, for the first time, the unpublished manuscripts of Lars Hormander, written between 1951 and 2007. Hormander himself organised the manuscripts and also wrote the notes explaining their origins, presenting the material in the for Olof Hörmander.

We provide an improvement of the H ormander multiplier theorem in which the Sobolev space Lr s (Rn) with integrability index r and smoothness index s > n=r is re-placed by the Sobolev space with smoothness s built upon the Lorentz space Ln=s;1(Rn). 1. Hormander’s Theorem Let L denote the operator L = 1 2 Xk i=1 X2 i + Y where X1,·,,Xk,Y are C∞ vector fields in Rn.Assume that the Lie Algebra generated by X1,·,,Xk,Y span Rn at every x.
