Causality in 3D massive gravity theories
Edelstein, Jose D.; Giribet, Gaston; Gomez, Carolina; Kilicarslan, Ercan; Leoni, Matias; Tekin, Bayram (2017-05-12)
We study the constraints coming from the local causality requirement in various 2 + 1 dimensional dynamical theories of gravity. In topologically massive gravity, with a single parity noninvariant massive degree of freedom, and in new massive gravity, with two massive spin-2 degrees of freedom, causality and unitarity are compatible with each other and both require the Newton's constant to be negative. In their extensions, such as the Born-Infeld gravity and the minimal massive gravity the situation is simi...
Causality in curved space
Aljasem Alashour, Bassem; Tekin, Bayram; Department of Physics (2018)
The notion of Causality is a key concept in formulating theories that describe real physical systems. So when a proposed model violates this concept this usually signals the existence of an error in the conceptual formulation or in the physical understanding of the results, which might indicate to us which models should we pursue, modify or drop all together. In this work the possibility of causality violations introduced by modifying Einstein gravity is studied using the idea of the time-delay introduced t...
CAUSALITY AND KALLEN-LEHMANN-LIKE REPRESENTATION OF THE FERMIONIC STRING PROPAGATOR
FAINBERG, VY; FILKOV, AL (1993-12-10)
A spectral representation for the Green's functions of the free fermionic Ramond-Neveu-Schwarz string is obtained. This representation is valid for any initial and final string configurations and it manifests an exponential growth of spectral densities intrinsic in nonlocalizable theories. The causal and singular properties of the propagators are considered.
Causality between market liquidity and depth for energy and grains
Sarı, Ramazan; Chang, Chia-Lin; MCaleer, Michael (2012-09-01)
This paper examines the roles of futures prices of crude oil, gasoline, ethanol, corn, soybeans and sugar in the energy-grain nexus. It also investigates the own- and cross-market impacts for the lagged grain trading volume and the open interest in the energy and grain markets. According to the results, the conventional view, for which the impacts are from oil to gasoline to ethanol to grains in the energy-grain nexus, does not hold well in the long run because the oil price is influenced by gasoline, soybe...
Causal and stable FIR-IIR Wiener filters
Tuncer, Temel Engin (2003-10-01)
IIR Wiener filters are the optimum filters with minimum MSE. In general, these filters are noncausal and their causal counterparts have larger MSE. In this paper, we propose causal and stable FIR-IIR Wiener filters which have the same MSE performance when the FIR part is sufficiently long. FIR-IIR Wiener filter employs the best delay LS inverse filter to model the noncausal part of the IIR Wiener filter. We have compared the MSE performances of IIR causal and noncausal, FIR best delay and FIR-IIR Wiener fil...
