We prove a version of Rothschild-Stein's theorem of lifting and approximation and some related results in the context of nonsmooth Hörmander's vector fields for which the highest order commutators are ...

The circumference of a sphere is measured to be 24 cm, with a possible error of 0.25 cm. Use the differential \(dV\) to estimate the maximum error in the calculated ...

The usual local central limit theorem provides an approximation for the probability for an iid sequence . The approximation is proportional to the lattice size of the underlying distribution of the ...
