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

STABILITY OF STELLAR SYSTEMS ORBITING SGR A*
Odessa Astronomical Publications, 2016 Path equations of different orbiting objects in the presence of very strong gravitational fields are essential to examine the impact of its gravitational effect on the stability of each system.

Indagationes Mathematicae (Proceedings), 1951 If one keeps angle but drops an invariant (four-dimensional) length from an essentially Einstenian description of the world, one gets Conformal Relativity. (The invariance of angle is all that is required by the «invariance of the light cone» for physically equivalent observers). The Special Theory of Conformal Relativity studies the conformal geometry,

Unifying the Galilei Relativity and the Special Relativity [PDF]
ISRN Mathematical Physics, 2013 We present two models combining some aspects of the Galilei and the Special relativities that lead to a unification of both relativities. This unification is founded on a reinterpretation of the absolute time of the Galilei relativity that is considered as a quantity in its own and not as mere reinterpretation of the time of the Special relativity in ...

Advancing physiology education by understanding the multiple dimensions of homeostasis
Frontiers in Physiology, 2023 Homeostasis of the internal environment has been considered the central organizing concept of physiology. However, current definitions of it in textbooks and online teaching sources do not sufficiently reflect how homeostasis serves its central unifying ...

International Journal of Modern Physics A, 2003 A possible resolution of the incompatibility of quantum mechanics and general relativity is that the relativity principle is emergent. I show that the central paradox of black holes also occurs at a liquid-vapor critical surface of a bose condensate but is resolved there by the phenomenon of quantum criticality.

ξRϕ2 coupling, cosmological constant and quantum gravitational corrections to Newton’s potential
Physics Letters BThis letter investigates the contribution of the −gξRϕ2 non-minimal interaction to the long range gravitational potential for massive scalar fields, found from the non-relativistic limit of the 2-2 scattering amplitude with graviton exchanges.

Reply to the Comment on ‘Quantum principle of relativity’
New Journal of Physics, 2023 We discuss critical remarks raised by Horodecki (2023 arXiv: 2301.07802 [quant-ph]) toward our work on the connection between superluminal extension of special relativity and fundamental aspects of quantum theory.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background General pediatricians often evaluate hematologic and oncologic presentations before subspecialty consultation, yet the 2025 Accreditation Council for Graduate Medical Education (ACGME) pediatric requirements reduce inpatient pediatric hematology/oncology (PHO) time, raising questions about resident readiness.
