Integration of Complex Vector Fields
(1.3) Lku = 0, k = 1,. . . , m. Any function u satisfying all the above equations must also satisfy the equations (1.4) [Lk9 Lh]u = LkLhu LhLku = 0. Thus it is reasonable to assume that the space spanned by the vector fields Lu..., Lm is closed under the bracket operation. Condition A. This condition is satisfied if (1.5) [Lk,IJ = I 4 ^ j where the a^6C°°((7). From (1.2) we obtain [Lk,Lh]u = Lk...
متن کاملconstruction of vector fields with positive lyapunov exponents
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
15 صفحه اولIntegration of Brownian vector fields
Using the Wiener chaos decomposition, we show that strong solutions of non Lipschitzian S.D.E.'s are given by random Markovian kernels. The example of Sobolev flows is studied in some detail, exhibiting interesting phase transitions. Résumé. Intégration de champs de vecteurs browniens. En utilisant la décomposition en chaos de Wiener, nous montrons que les solutions fortes d'E.D.S. non Lipschit...
متن کاملExplicit geometric integration of polynomial vector fields
We present a unified framework in which to study splitting methods for polynomial vector fields in R. The vector field is to be represented as a sum of shears, each of which can be integrated exactly, and each of which is a function of k < n variables. Each shear must also inherit the structure of the original vector field: we consider Hamiltonian, Poisson, and volumepreserving cases. Each case...
متن کاملSimple Vector Fields with Complex Behavior
We present a technique for constructing simple vector fields with complex behaviour and illustrate this technique with two examples. The examples we construct, besides describing partial behaviour of complicated systems, have an interest of their own as they illustrate complicated behaviour in a tractable way.
