Local Gevrey and Quasi - Analytic Hypoellipticity For
Introduction. The db complex is well defined on any smooth CR manifold M, and once a metric is fixed, so is the complex Laplace-Beltrami operator Db on forms of type (p, q). For compact M without boundary, the bb cohomology of M may be studied via Ub [6], and thus local smoothness of solutions to Dbu = ƒ is important. In its own right, Ub is a prototype of doubly characteristic operators. Under...
متن کاملNon-isotropic Gevrey Hypoellipticity for Grushin Operators
We shall determine non-isotropic Gevrey exponents for general Grushin operators based on the results given in the paper [26], where a method to determine isotropic (worst) Gevrey exponents was given. The ideas of the bracket calculus given in the paper [2] and FBI-transformation given in the paper [5] are also useful.
متن کاملThe Gevrey hypoellipticity for a class of kinetic equations
In this paper, we study the Gevrey regularity of weak solutions for a class of linear and semi-linear kinetic equations, which are the linear model of spatially inhomogeneous Boltzmann equations without an angular cutoff.
متن کاملThe Gevrey Hypoellipticity for Linear and Non-linear
In this paper, we study the Gevrey regularity of weak solution for a class of linear and semilinear Fokker-Planck equations.
متن کاملGevrey Hypoellipticity for Partial Differential Equations with Characteristics of Higher Multiplicity
We consider a class of partial differential equations with characteristics of constant multiplicity m ≥ 4. We prove for these equations a result of hypoellipticity and Gevrey hypoellipticity, by using classical Fourier integral operators and Sm ρ,δ arguments.
