Smooth Singularities Exposed: Chimeras of the Differential Spacetime Manifold
Anastasios Mallios, Ioannis Raptis
The smooth gravitational singularities of the differential spacetime manifold based General Relativity (GR) are viewed from the perspective of the background manifold independent a…
Finitary-Algebraic `Resolution' of the Inner Schwarzschild Singularity
Ioannis Raptis
A `resolution' of the interior singularity of the spherically symmetric Schwarzschild solution of the Einstein equations for the gravitational field of a point-particle is carried…
A Combinatory-Algebraic Perspective on Multipartiteness, Entanglement and Quantum Localization
Ioannis Raptis, Roman Zapatrin
We claim that both multipartiteness and localization of subsystems of compound quantum systems are of an essentially relative nature crucially depending on the set of operationalis…
Finitary, Causal and Quantal Vacuum Einstein Gravity
Anastasios Mallios, Ioannis Raptis
We continue recent work and formulate the gravitational vacuum Einstein equations over a locally finite spacetime by using the basic axiomatics, techniques, ideas and working philo…
Quantum Space-Time as a Quantum Causal Set
Ioannis Raptis
A recently proposed algebraic representation of the causal set model of the small-scale structure of space-time of Sorkin et al. is briefly reviewed and expanded. The algebraic mod…
`Mixed' Jordan-Lie Superalgebra
Ioannis Raptis
An algebra A not encountered in either the usual algebraic varieties or supervarieties is introduced. A is a graded and deformed version of the quaternions, with structure similar…
