Dark Energy and Inflation with Volume Normalized Action
Gregory Gabadadze, Siqing Yu
In the theories described by a volume normalized action functional, an arbitrary cosmological constant is eliminated from the physical picture of our Universe, and dynamical altern…
Nonlocal Galileons and Self-Acceleration
Gregory Gabadadze, Siqing Yu
A certain class of nonlocal theories eliminates an arbitrary cosmological constant (CC) from a universe that can be perceived as our world. Dark energy then cannot be explained by…
Metamorphosis of the Cosmological Constant and 5D Origin of the Fiducial Metric
Gregory Gabadadze, Siqing Yu
In a recently proposed theory, the cosmological constant (CC) does not curve spacetime in our universe, but instead gets absorbed into another universe endowed with its own dynamic…
Superluminal Vector in Ghost-free Massive Gravity
Siqing Yu
We present a classical analysis on the issue of vector superluminality in the decoupling limit ghost-free massive gravity with a Minkowski reference metric. We show explicitly in t…
