Intrinsic Taylor formula for non-homogeneous Kolmogorov-type Lie groups
Stefano Pagliarani, Michele Pignotti
We prove an intrinsic Taylor-like formula for a class of Lie groups arising in the study of some sub-elliptic differential operators, namely the Kolmogorov operators. The estimate…

Intrinsic expansions for averaged diffusion processes
S. Pagliarani, A. Pascucci, M. Pignotti
We show that the rate of convergence of asymptotic expansions for solutions of SDEs is generally higher in the case of degenerate (or partial) diffusion compared to the elliptic ca…

Intrinsic Taylor formula for Kolmogorov-type homogeneous groups
Stefano Pagliarani, Andrea Pascucci, Michele Pignotti
We consider a class of ultra-parabolic Kolmogorov-type operators satisfying the Hormander's condition. We prove an intrinsic Taylor formula with global and local bounds for the rem…
