terrà un seminario dal titolo:



*“**Hörmander operators in nondivergence form: a Landis-type approach**”*



*Abstract:*

In this talk we will discuss the validity of Harnack inequalities for linear
degenerate-elliptic equations of Hörmander type with non-smooth coefficients.
We are interested in operators in nondivergence form, for which the
analogous of the Krylov-Safonov Harnack inequality for equations with
bounded measurable coefficients is still unknown. We will show a
perturbative approach to prove invariant Harnack inequalities for operators
with coefficients satisfying either a Cordes-Landis assumption or a
continuity hypothesis. We will consider two specific classes of equations:
the first class is formed by degenerate-elliptic operators which are
horizontally elliptic with respect to Heisenberg-type vector fields; the
second one constitutes a class of evolution operators of
Kolmogorov-Fokker-Planck
type. This talk is mainly based on joint works with F. Abedin and C.E.
Gutiérrez.



Tutti gli interessati sono invitati a partecipare.
