Web2 mrt. 2024 · Novikov’s problem admits a natural formulation in terms of singular measured foliations on surfaces. The foliations are defined by the restriction of a differential 1-form on T3 with constant coefficients to a null-homologous surface. In mathematics, Novikov's compact leaf theorem, named after Sergei Novikov, states that A codimension-one foliation of a compact 3-manifold whose universal covering space is not contractible must have a compact leaf.

The global holonomy of a transversely oriented linear foliation F M U, of codimension strictly superior to 0, defined on a compact affine manifold (M, ∇ M) is not trivial. Proof. Suppose that the global holonomy h F M U: π 1 (M) → A f f (R n / U) is trivial. Let h U: R n → R n / U be the quotient map. 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. morphine category

"In probability theory, Novikov's condition is the sufficient condition for a stochastic process which takes the form of the Radon–Nikodym derivative in Girsanov's theorem to be a martingale. 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.
