construction 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 اولExplicit B-spline regularization in diffeomorphic image registration
Diffeomorphic mappings are central to image registration due largely to their topological properties and success in providing biologically plausible solutions to deformation and morphological estimation problems. Popular diffeomorphic image registration algorithms include those characterized by time-varying and constant velocity fields, and symmetrical considerations. Prior information in the f...
متن کاملKorn’s Inequalities for Piecewise H Vector Fields
Korn’s inequalities for piecewise H1 vector fields are established. They can be applied to classical nonconforming finite element methods, mortar methods and discontinuous Galerkin methods.

متن کاملTrivariate Spline Approximation of Divergence-free Vector Fields
We discuss the approximation properties of divergence-free vector fields by using trivariate spline vectors which are also divergence-free. We pay special attention to the approximation constants and show that they depend only on the smallest solid angle in the underlying tetrahedral partition and the nature of the boundary of the domain. The estimates are given in the max-norm and L norm. §
