TL;DR
This paper investigates the van Dam-Veltman-Zakharov discontinuity in topologically new massive gravity, showing how degrees of freedom change when transitioning from anti-de Sitter to Minkowski spacetime.
Contribution
It demonstrates the presence of VDVZ discontinuity in TNMG and interprets the reduction in degrees of freedom during the spacetime transition.
Findings
VDVZ discontinuity appears in TNMG
Reduction from 2 to 1 degree of freedom
Discontinuity occurs during transition from AdS to Minkowski
Abstract
We study van Dam-Veltman-Zakharov discontinuity in the topologically new massive gravity (TNMG). The reduction from 2 degrees of freedom to one is interpreted as van Dam-Veltman-Zakharov discontinuity appeared when going from anti-de Sitter spacetime to Minkowski spacetime in the linearized TNMG.
