(Sort of) Testing relativity with extreme mass ratio inspirals [PDF]
, 2006 The inspirals of ``small'' ($1 - 100 M_\odot$) compact bodies through highly relativistic orbits of massive (several $\times 10^5 M_\odot -$ several $\times 10^6 M_\odot$) black holes are among the most anticipated sources for the LISA gravitational-wave

Relative and modified relative realizability
Annals of Pure and Applied Logic, 2002 The notion of relative realizability, originally due to Kleene and Vesley, has recently been studied in topos-theoretic terms by the first author of this paper together with \textit{S. Awodey} and \textit{D. S. Scott} [``Local realizability toposes and a modal logic for computability'', Math. Struct. Comput. Sci.

Relative torsion classes, relative tilting, and relative silting modules
Communications in Algebra, 2021 Let $Λ$ be an Artin algebra. In 2014, T. Adachi, O. Iyama and I. Reiten proved that the torsion funtorially finite classes in $\mathrm{mod}\,(Λ)$ can be described by the $τ$-tilting theory. The aim of this paper is to introduce the notion of $F$-torsion class in $\mathrm{mod}\,(Λ)$, where $F$ is an additive subfunctor of $\mathrm{Ext}^1_Λ,$ and to ...

The relativity of relative risks: disadvantage or opportunity? [PDF]
British Journal of Psychiatry, 2003 Psychiatric epidemiologists use many tools, such as relative risks and the related odds ratios, that were developed to study chronic somatic disease. Cancer epidemiologists identify as a major advantage of relative risks that, when appropriately adjusted for confounding and effect modification ...

Physical Review E, 2016 When studying thermalization of quantum systems, it is typical to ask whether a system interacting with an environment will evolve towards a local thermal state. Here, we show that a more general and relevant question is "when does a system thermalize relative to a particular reference?" By relative thermalization we mean that, as well as being in a ...

RELATIVITY GROUPOID INSTEAD OF RELATIVITY GROUP [PDF]
International Journal of Geometric Methods in Modern Physics, 2007 In 1908, Minkowski [13] used space-like binary velocity-field of a medium, relative to an observer. In 1974, Hestenes introduced, within a Clifford algebra, an axiomatic binary relative velocity as a Minkowski bivector [7, 8]. We propose to consider binary relative velocity as a traceless nilpotent endomorphism in an operator algebra. Any concept of a

Patient-Relativity in Morality [PDF]
, 2016 It is common to distinguish moral rules, reasons, or values that are agent-relative from those that are agent-neutral. One can also distinguish moral rules, reasons, or values that are moment-relative from those that are moment-neutral.

Strong-Coupled Relativity Without Relativity [PDF]
General Relativity and Gravitation, 2004 GR can be interpreted as a theory of evolving 3-geometries. A recent such formulation, the 3-space approach of Barbour, Foster and Ó Murchadha, also permits the construction of a limited number of other theories of evolving 3-geometries, including conformal gravity and strong gravity.

A logic road from special relativity to general relativity
, 2011 We present a streamlined axiom system of special relativity in first-order logic. From this axiom system we "derive" an axiom system of general relativity in two natural steps. We will also see how the axioms of special relativity transform into those of

Covariant BSSN formulation in bimetric relativity
, 2020 Numerical integration of the field equations in bimetric relativity is necessary to obtain solutions describing realistic systems. Thus, it is crucial to recast the equations as a well-posed problem.
