We study solitons of almost pseudo symmetric Kählerian space-time manifold. It is considered that different curvature tensors like projective, conharmonic and conformal curvature tensors in almost pseudo symmetric Kählerian space-time manifolds are flat. It is shown that solitons are steady, expanding or shrinking under different relations of isotropic pressure, the cosmological constant, energy density and gravitational constant.

凯勒时空流形的孤子

我们研究了几乎伪对称的 Kählerian 时空流形的孤子。几乎伪对称的 Kählerian 时空流形中的不同曲率张量，如射影曲率张量、共调曲率张量和共形曲率张量被认为是平坦的。结果表明，在各向同性压力、宇宙学常数、能量密度和引力常数的不同关系下，孤子是稳定的、膨胀的或收缩的。
