本文旨在找出遠距平行重力理論中,所有可能的 pp-波時空對稱群,並與廣義相對論中的結果進行比較。
This research paper explores the symmetry groups of plane-fronted gravitational waves (pp-waves) within the framework of teleparallel gravity, an alternative theory of gravity. The authors utilize symmetry methods and the Cartan-Karlhede algorithm to identify all permissible symmetry groups for these spacetimes, uncovering previously overlooked solutions in both teleparallel gravity and general relativity.
This study reconstructs the scalar field potential necessary for an extended matter bounce scenario within the framework of f(T, ϕ) gravity, a modified teleparallel gravity theory, and explores its cosmological implications using two specific functional forms of the torsion scalar.
본 논문은 텔레평행 중력의 뉴턴 극한에서 비틀림이 반드시 사라진다는 최근 논문의 주장을 반박하며, 명확한 반례를 제시하고 원 논문의 증명 과정에서의 오류를 지적합니다.
