Smoothing singular constant scalar curvature Kähler surfaces and minimal Lagrangians
International audienceGiven a complex surface X with singularities of class T and no nontrivial holomorphic vector field, endowed with a Kähler class Ω 0 , we consider smoothings (M t , Ω t ), where Ω t is a Kähler class on M t degenerating to Ω 0 .Under

In this paper, from the viewpoint of submanifold theory, we study the isolation phenomena of Riemannian manifolds with constant scalar curvature and vanishing Weyl conformal curvature tensor.

Effective Gravitational “Constant” in Scalar-(Curvature)Tensor and Scalar-Torsion Gravities
In theories where a scalar field couples nonminimally to gravity, the effective gravitational “constant” becomes dependent on the value of the scalar field.

Constant scalar curvature Kähler metrics on rational surfaces [PDF]
We consider projective rational strong Calabi dream surfaces: projective smooth rational surfaces which admit a constant scalar curvature Kähler metric for every Kähler class.

Randers Metrics of Constant Scalar Curvature
Abstract.Randers metrics are a special class of Finsler metrics. Every Randers metric can be expressed in terms of a Riemannian metric and a vector field via Zermelo navigation. In this paper, we show that a Randers metric has constant scalar curvature if the Riemannian metric has constant scalar curvature and the vector field is ...

On the resolution of extremal and constant scalar curvature Kaehler orbifolds [PDF]
In this paper we give sufficient conditions on a compact orbifold with an extremal Kaehler metric to admit a resolution with an extremal Kaehler metric. We also complete the Kaehler constant scalar curvature case.

Uniqueness of constant scalar curvature Sasakian metrics [PDF]
In this paper, we prove that the transverse Mabuchi K-energy functional is convex along the weak geodesic in the space of Sasakian metrics. As an application, we obtain the uniqueness of constant scalar curvature Sasakian metrics modulo automorphisms for

On generalized m-quasi-Einstein manifolds with constant scalar curvature
We study generalized m-quasi-Einstein manifolds with constant scalar curvature. First, we establish a classification of generalized m-quasi-Einstein manifolds with parallel Ricci tensor. Second, and particularly, if an m-quasi-Einstein manifold possesses

Spherically symmetric space–times with constant curvature scalar
In view of the geometrical importance of spaces with constant scalar curvature, a systematic study of spherically symmetric such space–time manifolds with respect to the eigenvalues of the Ricci tensor is made. The cases of two double or one quadruple eigenvalue are treated exhaustively.

Constant Scalar Curvature of Toric Fibrations
We study the conditions under which a fibration of toric varieties, fibered over a flag variety, admits a constant scalar curvature Kähler metric. We first provide an introduction to toric varieties and toric fibrations and derive the scalar curvature equation.
