Regularity near the Initial State in the Obstacle Problem for a class of Hypoelliptic Ultraparabolic Operators
نویسندگان
چکیده
This paper is devoted to a proof of regularity, near the initial state, for solutions to the Cauchy-Dirichlet and obstacle problem for a class of second order differential operators of Kolmogorov type. The approach used here is general enough to allow us to consider smooth obstacles as well as non-smooth obstacles. 2000 Mathematics Subject classification: 35R35, 35K70, 35R03, 35Q91

The obstacle problem for a class of hypoelliptic ultraparabolic equations
We prove that the obstacle problem for a non-uniformly parabolic operator of Kolmogorov type, with Cauchy (or Cauchy-Dirichlet) boundary conditions, has a unique strong solution u. We also show that u is a solution in the viscosity sense.
متن کاملAn Inhomogeneous Dirichlet Problem for a Non-hypoelliptic Linear Partial Differential Operator
In this paper we state an inhomogeneous Dirichlet problem for a class of linear partial diierential operators which are non-hypoelliptic. We prove uniqueness, existence and regularity results for its solutions.
متن کاملproperties of M−hyoellipticity for pseudo differential operators
In this paper we study properties of symbols such that these belong to class of symbols sitting insideSm ρ,φ that we shall introduce as the following. So for because hypoelliptic pseudodifferential operatorsplays a key role in quantum mechanics we will investigate some properties of M−hypoelliptic pseudodifferential operators for which define base on this class of symbols. Also we consider maxi...
متن کاملA Parametrix for Kohn’s Operator
Recently, Kohn constructed examples of sums of squares of complex vector fields satisfying Hörmander’s condition that lose derivatives, but are nevertheless hypoelliptic. He also demonstrated optimal L2 regularity. In this paper, we construct parametricies for Kohn’s operators, which lead to the corresponding Lp (1 < p < ∞) and Lipschitz regularity. In fact, our parametrix construction generali...
متن کاملThe Index of Hypoelliptic Operators on Foliated Manifolds
In [EE1] and [EE2] we presented the solution to the index problem for a natural class of hypoelliptic differential operators on compact contact manifolds. The methods developed to deal with that problem have wider applicability to the index theory of hypoelliptic Fredholm operators. As an example of the power of the proof techniques we present here a new proof of a little known index theorem of...
