Connecting noncommutative geometry to f(R) modified gravity
Peter K. F. Kuhfittig
It is shown in this note that a noncommutative-geometry background determines the modified-gravity function for modeling dark matter.
Spherically symmetric wormholes of embedding class one
Peter K. F. Kuhfittig
This paper generalizes an earlier result by the author based on well-established embedding theorems that connect the classical theory of relativity to higher-dimensional spacetimes…
Traversable wormholes sustained by an extra spatial dimension
Peter K. F. Kuhfittig
This paper explores the effect of an extra spatial dimension on a Morris-Thorne wormhole. After proposing a suitable model, it is shown that under certain conditions, the throat of…
A model for dark energy based on the theory of embedding
Peter K. F. Kuhfittig, Vance D. Gladney
A long-standing topic of interest in the general theory of relativity is the embedding of curved spacetimes in higher-dimensional flat spacetimes. The main purpose this paper is to…
Two diverse models of embedding class one
Peter K. F. Kuhfittig
Embedding theorems have continued to be a topic of interest in the general theory of relativity since these help connect the classical theory to higher-dimensional manifolds. This…
Wormholes in f(R) gravity with a noncommutative-geometry background
Peter K. F. Kuhfittig
This paper discusses the possible existence of traversable wormholes in f(R) modified gravity while assuming a noncommutative-geometry background, as well as zero tidal forces. The…
