TL;DR
This paper introduces a nonlinear multigravity theory and explores its cosmological implications, revealing that the universe's scale factors exhibit repeating phases of acceleration and deceleration.
Contribution
It presents a novel nonlinear multigravity framework and applies it to cosmology, demonstrating dynamic scale factor behavior.
Findings
Scale factors show repeating acceleration and deceleration phases.
The theory provides a new approach to multigravity cosmology.
Abstract
We have constructed a nonlinear multi-graviton theory. An application of this theory to cosmology is discussed. We found that scale factors in a solution for this theory repeat acceleration and deceleration.
