A Lipschitz condition along a transversal foliation implies local uniqueness for ODEs
Electronic Journal of Qualitative Theory of Differential Equations, 2018 We prove the following result: if a continuous vector field $F$ is Lipschitz when restricted to the hypersurfaces determined by a suitable foliation and a transversal condition is satisfied at the initial condition, then $F$ determines a locally unique ...

Dimensional reduction to hypersurface of foliation [PDF]
, 2013 When the bulk spacetime has a foliation structure, the collective dynamics of the hypersurfaces should reveal certain aspects of the bulk physics. The procedure of reducing the bulk to a hypersurface, called ADM reduction, was implemented in [3] where ...

Rapid evolution of complex limit cycles [PDF]
, 2009 The current article studies certain problems related to complex cycles of holomorphic foliations with singularities in the complex plane. We focus on the case when polynomial differential one-form gives rise to a foliation by Riemann surfaces.

Reduction of BTZ spacetime to hypersurfaces of foliation [PDF]
, 2013 A bstractWe reduce the BTZ spacetime to two kinds of hypersurfaces of foliation: one having a fixed radial coordinate and the other a fixed angular coordinate. The radial reduction leads to a Liouville type theory, and confirms, from the first principle,

Willmore-type variational problem for foliated hypersurfaces
Electronic Research ArchiveAfter Thomas James Willmore, many authors were looking for an immersion of a manifold in Euclidean space or Riemannian manifold, which is the critical point of functionals whose integrands depend on the mean curvature or the norm of the second ...

A unified approach to compute foliations, inertial manifolds, and tracking initial conditions [PDF]
, 2012 Several algorithms are presented for the accurate computation of the leaves in the foliation of an ODE near a hyperbolic fixed point. They are variations of a contraction mapping method in [25] to compute inertial manifolds, which represents a particular

On a foliation-covariant elliptic operator on null hypersurfaces [PDF]
, 2013 We introduce a new elliptic operator on null hypersurfaces of four-dimensional Lorentzian manifolds. This operator depends on the first and second fundamental forms of the sections of a foliation of the null hypersurface and its novelty originates from ...

On the strong homotopy Lie–Rinehart algebra of a foliation [PDF]
, 2012 It is well known that a foliation of a smooth manifold M gives rise to a rich cohomological theory, its characteristic (i.e. leafwise) cohomology. Characteristic cohomologies of may be interpreted, to some extent, as functions on the space P of integral ...
