Z-Solitons and Gradient Z-Solitons on α-Cosymplectic Manifolds

open access: yesAxioms
In this paper, we study Z-solitons and gradient Z-solitons on α-cosymplectic manifolds. The soliton structure is defined by the generalized tensor Z=S+βg, where S denotes the Ricci tensor, g the metric tensor, and β a smooth function.

Classification of Three-Dimensional Contact Metric Manifolds with Almost-Generalized Ƶ-Solitons

open access: yesMathematics
This work investigates the classification of three-dimensional complete contact metric manifolds that are non-Sasakian and satisfy the relation Qξ=σξ, focusing on those that support an almost-generalized Ƶ-soliton. In the scenario where σ is constant, we

Sasakian Geometry, Holonomy, and Supersymmetry

open access: yes, 2007
In this expository article we discuss the relations between Sasakian geometry, reduced holonomy and supersymmetry. It is well known that the Riemannian manifolds other than the round spheres that admit real Killing spinors are precisely Sasaki-Einstein ...
