Relative Select

open access: yes, 2015
Motivated by the problem of storing coloured de Bruijn graphs, we show how, if we can already support fast select queries on one string, then we can store a little extra information and support fairly fast select queries on a similar string.

Relative collaring [PDF]

open access: yesProceedings of the American Mathematical Society, 1976
It was proved by Morton Brown that the boundary of a manifold has a collar neighborhood. Later Robert Connelly gave a different proof of that result, and his method of proof was used by T. Benny Rushing to prove a relative collaring theorem. This paper contains a relative collaring theorem that is more general than either of the two just mentioned.

Quantum Foam, Gravity and Gravitational Waves

open access: yes, 2003
The new information-theoretic Process Physics has shown that space is a quantum foam system with gravity being, in effect, an inhomogeneous in-flow of the quantum foam into matter.

Relative currents [PDF]

open access: yesConformal Geometry and Dynamics of the American Mathematical Society, 2017
In this paper we define currents relative to a free factor system. We prove that a fully irreducible outer automorphism relative to a free factor system acts with uniform north-south dynamics on a subspace of the space of projective relative currents.

Space and Time as Relations: The Theoretical Approach of Leibniz

open access: yesPhilosophies, 2018
The epistemological rupture of Copernicus, the laws of planetary motions of Kepler, the comprehensive physical observations of Galileo and Huygens, the conception of relativity, and the physical theory of Newton were components of an extremely fertile ...

The Tragic Downfall and Peculiar Revival of Quaternions

open access: yesMathematics
On October 16th 1843, the prominent Irish mathematician Sir William Rowan Hamilton, in an inspired act of vandalism, carved his famous i2=j2=k2=ijk=−1 on the Brougham Bridge in Dublin, thus starting a major clash of ideas with the potential to change the

Energy Conservation in a Charged Retarded Field Engine

open access: yesEnergies
Energy conservation, rooted in the time invariance of physical laws and formalized by Noether’s theorem, requires that systems with space-time translational symmetry conserve momentum and energy. This work examines how this principle applies to a charged
