Acausality and Nonunique Evolution in Generalized Teleparallel Gravity
Keisuke Izumi, Je-An Gu, Yen Chin Ong
We show the existence of physical superluminal modes and acausality in the Brans-Dicke type of extension of teleparallel gravity that includes F(T) gravity and teleparallel dark en…
The Fate of Monsters in Anti-de Sitter Spacetime
Yen Chin Ong, Pisin Chen
Black hole entropy remains a deep puzzle: where does such enormous amount of entropy come from? Curiously, there exist gravitational configurations that possess even larger entropy…
An Analysis of Characteristics in Non-Linear Massive Gravity
Keisuke Izumi, Yen Chin Ong
We study the Cauchy problem in a special case of non-linear massive gravity: the two-tensor "f-g" theory. Despite being ghost-free, it has recently been argued that the theory is i…
Problems with Propagation and Time Evolution in f(T) Gravity
Yen Chin Ong, Keisuke Izumi, James M. Nester +1
Teleparallel theories of gravity have a long history. They include a special case referred to as the Teleparallel Equivalent of General Relativity (TEGR, aka GR). Recently t…
Seiberg-Witten Instability of Various Topological Black Holes
Yen Chin Ong, Pisin Chen
We review the Seiberg-Witten instability of topological black holes in Anti-de Sitter space due to nucleation of brane-anti-brane pairs. We start with black holes in general relati…
