Abstract.As it is known, Einstein manifolds play an important role in geometry as well as in general relativity. Einstein manifolds form a natural subclass of the class of quasi-Einstein manifolds. In ...
Vertex operator algebras (VOAs) lie at the intersection of mathematics and theoretical physics, providing a rigorous algebraic framework for two-dimensional conformal field theories (CFTs). These ...
In the present article we find the nature of N(κ)-contact metric manifolds admitting Riemann solitons with some restrictions on the potential vector fields. The cases, when the potential vector field ...
