WebIf a –manifold contains a non-separating sphere, then some twisted Heegaard Floer homology of is zero. This simple fact allows us to prove several results about Dehn surgery on knots in such manifolds. Similar result… WebThe Molino structure theorem for foliations defined by nonsingular Maurer-Cartan forms is treated in Chapter 4. A holonomy groupoid of a foliation is a basic example of so called Lie groupoids. The last two chapters describe properties of Lie groupoids, a notion of weak equivalence between Lie groupoids, a special class of étale groupoids, and a Lie …

If satisfied together with other conditions, Girsanov's theorem may be applied to a Brownian motion stochastic process to change from the original measure to the new measure defined by the Radon–Nikodym derivative.
WebThis condition was suggested and proved by Alexander Novikov. There are other results which may be used to show that the Radon–Nikodym derivative is a martingale, such as the more general criterion Kazamaki's condition, however Novikov's condition is the … WebNovikov's theorem states that, given a taut (codimension-one) foliation on a closed 3-manifold M, the fundamental group of any leaf injects into the fundamental group of M.
