Quadrature rules and distribution of points on manifolds
Luca Brandolini, Christine Choirat, Leonardo Colzani +3
We study the error in quadrature rules on a compact manifold. As in the Koksma-Hlawka inequality, we consider a discrepancy of the sampling points and a generalized variation of th…
On the lifting and approximation theorem for nonsmooth vector fields
Marco Bramanti, Luca Brandolini, Marco Pedroni
We prove a version of Rothschild-Stein's theorem of lifting and approximation and some related results in the context of nonsmooth Hormander's vector fields for which the highest o…
Convolution operators defined by singular measures on the motion group
Luca Brandolini, Giacomo Gigante, Sundaram Thangavelu +1
This paper contains an improving result for convolution operators defined by singular measures associated to hypersurfaces on the motion group. This needs only mild geometr…
