DOI: 10.1088/1361-6382/aacddc
Abstract: In this paper, a noncommutative gravitational theory is constructed by applying Moyal deformation quantization and the Seiberg-Witten map to teleparallel gravity, a classical gravitational theory, as a gauge theory of local translational symmetry. Since our… read more here.

DOI: 10.1088/1475-7516/2018/05/052
Abstract: We investigate the evolution of scalar perturbations in f(T) teleparallel gravity and its effects on the cosmic microwave background (CMB) anisotropy. The f(T) gravity generalizes the teleparallel gravity which is formulated on the Weitzenbock spacetime,… read more here.
