The 17 invited examine articles during this quantity, all written via top specialists of their respective fields, are devoted to the nice French mathematician Jean Leray. quite a lot of issues with major new
results---detailed proofs---are provided within the components of partial differential equations, complicated research, and mathematical physics. Key topics are: * taken care of from the mathematical physics standpoint: nonlinear stability
of an increasing universe, the compressible Euler equation, spin teams and the Leray--Maslov index, * associated with the Cauchy challenge: an intermediate case among potent hyperbolicity and the Levi , global
Cauchy--Kowalewski theorem in a few Gevrey sessions, the analytic continuation of the resolution, worthwhile stipulations for hyperbolic structures, good posedness within the Gevrey category, uniformly diagonalizable structures and reduced
measurement, and monodromy of ramified Cauchy challenge. extra articles research effects on: * neighborhood solvability for a process of partial differential operators, * The hypoellipticity of moment order operators, *
Differential varieties and Hodge idea on analytic areas, * Subelliptic operators and sub- Riemannian geometry. participants: V. Ancona, R. Beals, A. Bove, R. Camales, Y. Choquet- Bruhat, F. Colombini, M. De Gosson, S. De
