On the ambiguity in the notion of transverse traceless modes of gravitational waves
Abhay Ashtekar, Béatrice Bonga
Somewhat surprisingly, in many of the widely used monographs and review articles the term Transverse-Traceless modes of linearized gravitational waves is used to denote two entirel…
On a basic conceptual confusion in gravitational radiation theory
Abhay Ashtekar, Béatrice Bonga
In much of the literature on linearized gravitational waves two completely different notions are called transverse traceless modes and labelled , often in different se…
Implications of a positive cosmological constant for general relativity
Abhay Ashtekar
Most of the literature on general relativity over the last century assumes that the cosmological constant is zero. However, by now independent observations have led to a consen…
