For hypoelliptic operators, the associated “Ricci curva-ture” takes on the value −∞ at points of degeneracy of the semi-Riemannian metric. For this reason, the standard proofs for the elliptic theory fail in the hypoelliptic setting. This paper presents recent results for hypoelliptic operators. Malliavin

WebThis book concerns the spectral theory of global hypoelliptic pseudodifferential operators in Rn and the asymptotic estimate of the eigenvalue distribution function N(l) of a hypoelliptic differential operator with polynomial coefficients in Rn. WebEvery elliptic operator with coefficients is hypoelliptic. In particular, the Laplacian is an example of a hypoelliptic operator (the Laplacian is also analytically hypoelliptic). In addition, the operator for the heat equation ( P ( u ) = u t − k Δ u {\displaystyle P(u)=u_{t}-k\,\Delta … WebNecessary and sufficient conditions for the hypoellipticity of an ordinary differential operator withC ∞ coefficients in a neighborhood of a zero of finite order of the leading term are given. A sufficient condition for such an operator to be in a certain Hormander class is also given. firma gmbhg
