On Generalized Douglas-Weyl $(\\alpha, \\beta)$-Metrics In this paper, we study generalized Douglas-Weyl $(\\alpha, \\beta)$-metrics.Suppose that an regular $(\\alpha, \\beta)$-metric $F$ is not of Randers type... A Tayebi,H Sadeghi 被引量: 18发表: 2015年 On projective invari...
Furthermore, we construct a family of generalized Douglas-Weyl Randers metrics which are not R -quadratic. We show that the Randers metric induced by a Kenmotsu manifold is a Douglas metric which is not of isotropic S -curvature. We show that the Randers metric induced by a Kenmotsu or ...
Central charges of higher-rank F-theory SCFTs were first computed in [37] using holographic methods. For the rank-ntheory of type\mathfrak {g}, theaandcWeyl anomaly coefficients and the\mathfrak {su}(2)and\mathfrak {g}flavor central charges were computed to take the following values: ...

We study the Yang–Mills measure on the sphere with unitary structure group. In the limit where the structure group has high dimension, we show that t
We prove a rigidity result for homogeneous generalized Douglas–Weyl metrics of Landsberg-type. We show that such metrics have constant \\(\\mathbf{H}\\) -curvature along geodesics. Then, we prove that every homogeneous D-recurrent Finsler metric is a Douglas metric. It turns out that a ...
We study a class of Finsler metrics whose Douglas curvature is constant along any Finslerian geodesics. This class of Finsler metrics is a subclass of the class of generalized Douglas-Weyl metrics and contains the class of Douglas metrics as a special case. We find a condition under which ...
