Lightlike foliations of semi-Riemannian manifolds [PDF]
arXiv, 2006 Using screen distributions and lightlike transversal vector bundles we develop a theory of degenerate foliations of semi-Riemannian manifolds.

Differential geometry of fibre bundles over foliated manifolds [PDF]
arXiv, 2001 Any leafwise connection on a fibre bundle over a foliated manifold is proved to come from a connection on this fibre bundle.

Tori Embedded in S3 with Dense Asymptotic Lines [PDF]
arXiv, 2008 In this paper are given examples of tori T^2 embedded in S^3 with all their asymptotic lines dense.

Parabolic foliations on 3-manifolds [PDF]
arXiv, 2008 In the paper we prove that every closed orientable three-manifold admits a parabolic foliation.

On the extrinsic geometry of contact structures [PDF]
arXiv, 2008 In the paper we prove, that extrinsic curvature does not impose restrictions on the topology of a contact structure, except the obvious ones.

On the existence of harmonic morphisms from three-dimensional Lie groups [PDF]
arXiv, 2010 In this paper we classify those three-dimensional Riemannian Lie groups which admit harmonic morphisms to surfaces.

On homogeneous composed Clifford foliations [PDF]
arXiv, 2015 We complete the classification, initiated by the second named author, of homogeneous singular Riemannian foliations of spheres that are lifts of foliations produced from Clifford systems.

Algebraic nature of singular Riemannian foliations in spheres [PDF]
arXiv, 2015 We prove that singular Riemannian foliations in Euclidean spheres can be defined by polynomial equations.

Pseudo-orbits, pseudoleaves and geometric entropy of foliations [PDF]
arXiv, 1996 We show that the entropy of a finitely generated pseudogroup (resp., of a foliation of a compact Riemannian manifold) can be calculated by suitable counting separated pseudo-orbits (resp., pseudoleaves).
