High order weak approximation schemes for Lévy-driven SDEs
Levy-driven stochastic di erential equation Euler scheme
2011/2/28
We propose new jump-adapted weak approximation schemes for stochas-tic di erential equations driven by pure-jump Levy processes.
A cohomological obstruction to weak approximation for homogeneous spaces
Brauer-Manin obstruction weak approximation homogeneous spaces
2011/1/19
Let X be a homogeneous space, X = G/H, where G is a connected linear algebraic group over a number field k, and H G is a k-subgroup (not necessarily con-nected). Let S be a finite set of places of k...
