Louis Boutet de Monvel

Université Pierre et Marie Curie, Paris, France~Professor of Mathematics. Contributed over four decades to elliptic operator theory, Cauchy-Riemann geometry, and the microlocal analysis of Bergman and Szegö projectors on pseudoconvex domains, producing unexpected results that reach into many areas of modern analysis. Work on elliptical boundary value problems extended the classical theory to the pseudodifferential operator setting, leading to major improvements in classical results. CR embedding theorem as well as fundamental work with Johannes Sjöstrand on the Bergman and Szegö kernels were milestones in the modern approach to complex analysis in several variables. Contributions to index theory for Toeplitz operators enabled equal treatment for smooth and real analytic versions of this theory. Joint monograph on the spectral theory of Toeplitz operators settled a major unsolved problem in spectral asymptotics for Zoll manifolds and became a foundation text in deformation quantization. Most recently, proved that an invariant for contact manifolds, which had intrigued researchers for more than a decade, is identically zero. Awarded the Médaille Émile Picard by the French Académie des sciences (2007).~
