Resource-distribution via Boolean constraints
James Harland, David Pym
We consider the problem of searching for proofs in sequential presentations of logics with multiplicative (or intensional) connectives. Specifically, we start with the multiplicati…
Torsion waves in metric-affine field theory
Alastair D. King, Dmitri Vassiliev
The approach of metric-affine field theory is to define spacetime as a real oriented 4-manifold equipped with a metric and an affine connection. The 10 independent components of th…
Microstructure Effects on Daily Return Volatility in Financial Markets
Andreas Krause
We simulate a series of daily returns from intraday price movements initiated by microstructure elements. Significant evidence is found that daily returns and daily return volatili…
Transport Properties of Highly Aligned Polymer Light-Emitting-Diodes
A. Kambili, A. B. Walker
We investigate hole transport in polymer light-emitting-diodes in which the emissive layer is made of liquid-crystalline polymer chains aligned perpendicular to the direction of tr…
A tensor interpretation of the 2D Dirac equation
Dmitri Vassiliev
We consider the Dirac equation in flat Minkowski 3-space and rewrite it as the Maxwell equation in Minkowski 4-space with torsion. The torsion tensor is defined as the dual of the…
Das Titsgebaeude von Siegelschen Modulgruppen vom Geschlecht 2
M. Friedland, G. K. Sankaran
We calculate Tits buildings for certain arithmetic subgroups of Sp(4). These give information about the boundary of the corresponding moduli spaces of abelian surfaces. More pictur…
