BIHARMONIC SUBMANIFOLDS IN 3-DIMENSIONAL (κ,µ)-MANIFOLDS

TL;DR: In this article, the authors give necessary and sufficient conditions for nonharmonic Legendre curves and anti-invariant surfaces of 3-dimensional (κ,μ)-manifolds to be bi-harmonic.

Topological contact dynamics I: symplectization and applications of the energy-capacity inequality

TL;DR: In this paper, the authors introduce topological contact dynamics of a smooth manifold carrying a cooriented contact structure, generalizing previous work in the case of a symplectic structure [MO07] or a contact form [BS12].

Second Order Parallel Tensors on Almost Kenmotsu Manifolds Satisfying the Nullity Distributions

TL;DR: In this article, it was shown that if there exists a second order symmetric parallel tensor on an almost Kenmotsu manifold, whose characteristic vector field belongs to the $(k,\mu)'$-nullity distribution, then either the manifold is locally isometric to the Riemannian product of an n+1)$-dimensional manifold of constant sectional curvature, or the second order tensor is a constant multiple of the associated metric tensor of the manifold.

Topology of locally conformally Kahler manifolds with potential

TL;DR: In this paper, it was shown that the existence of a potential can be characterized cohomologically as a vanishing of a certain cohomology class, called the Bott-Chern class.

Harmonicity and minimality of oriented distributions

TL;DR: In this article, an oriented distribution of S4m+3 tangent to the quaternionic Hopf fibration is shown to define a harmonic map and a minimal immersion.
