Hormander Operators
ISBN: 9789811261688 / Angielski / Twarda / 2022 / 724 str. Termin realizacji zamówienia: ok. 30 dni roboczych. Hörmander operators are a class of linear second order partial differential operators with nonnegative characteristic form and smooth coefficients, which are usually degenerate elliptic-parabolic, but nevertheless hypoelliptic, that is highly regularizing. The study of these operators began with the 1967 fundamental paper by Lars Hörmander and is intimately connected to the geometry of vector fields.Motivations for the study of Hörmander operators come for instance from Kolmogorov-Fokker-Planck equations arising from modeling physical systems governed by stochastic equations and the...

Fundamental Solutions and Local Solvability for Nonsmooth Hormander's Operators
ISBN: 9781470425593 / Angielski Termin realizacji zamówienia: ok. 30 dni roboczych. The authors consider operators of the form $L=sum_{i=1}^X_^+X_$ in a bounded domain of $mathbb^$ where $X_,X_,ldots,X_$ are nonsmooth Hormander's vector fields of step $r$ such that the highest order commutators are only Holder continuous. Applying Levi's parametrix method the authors construct a local fundamental solution $gamma$ for $L$ and provide growth estimates for $gamma$ and its first derivatives with respect to the vector fields. Requiring the existence of one more derivative of the coefficients the authors prove that $gamma$ also possesses second...
