Impact of Ambient Conformal Vector Fields on Yamabe Solitons on Riemannian Hypersurfaces
MathematicsWe investigate Yamabe solitons on Riemannian hypersurfaces induced by conformal vector fields in Riemannian and Lorentzian manifolds, with an emphasis on the tangential component.

Contact pairs and locally conformally symplectic structures [PDF]
, 2010 We discuss a correspondence between certain contact pairs on the one hand, and certain locally conformally symplectic forms on the other. In particular, we characterize these structures through suspensions of contactomorphisms.

Hermitian conformal classes and almost Kähler structures on 4-manifolds
Differential Geometry and its Applications, 1999 The authors prove that on most compact complex surfaces which admit symplectic forms, each Hermitian conformal class contains almost Kähler metrics. The number of symplectic forms compatible with a given metric can also be described. For precise formulations of the results, the reader should see the original paper, where many motivations are also ...

Holomorphic harmonic morphisms from cosymplectic almost Hermitian manifolds [PDF]
, 2014 We study 4-dimensional Riemannian manifolds equipped with a minimal and conformal foliation $\mathcal F$ of codimension 2. We prove that the two adapted almost Hermitian structures $J_1$ and $J_2$ are both cosymplectic if and only if $\mathcal F$ is ...

Selfdual Einstein metrics and conformal submersions [PDF]
, 2000 Weyl derivatives, Weyl-Lie derivatives and conformal submersions are defined, then used to generalize the Jones-Tod correspondence between selfdual 4-manifolds with symmetry and Einstein-Weyl 3-manifolds with an abelian monopole.

Conformal Dirichlet-Neumann Maps and Poincar\'e-Einstein Manifolds [PDF]
, 2007 A conformal description of Poincare-Einstein manifolds is developed: these structures are seen to be a special case of a natural weakening of the Einstein condition termed an almost Einstein structure.

Lightlike Hypersurfaces on Manifolds Endowed with a Conformal Structure of Lorentzian Signature
Acta Applicandae Mathematica, 1999 The authors study the geometry of lightlike hypersurfaces on manifolds $(M, c)$ endowed with a pseudoconformal structure $c = CO (n - 1, 1)$ of Lorentzian signature. Such hypersurfaces are of interest in general relativity since they can be models of different types of physical horizons.
