A construction of algebraic surfaces with many real nodes
singularities of surfaces real algebraic geometry Algebraic Geometry
2011/9/14
Abstract: A family of algebraic surfaces with many nondegenerate real singularities is introduced with the help of a construction that has been used in previous works for the generation of substitutio...
Pluri-potential theory on Grauert tubes of real analytic Riemannian manifolds, I
Pluri-potential theory Grauert tubes analytic Riemannian manifolds
2011/8/24
Abstract: We develop analogues for Grauert tubes of real analytic Riemannian manifolds (M,g) of some basic notions of pluri-potential theory, such as the Siciak extremal function. The basic idea is to...

Cognitive biological structures, social organizations, and computing machines operating in real time are subject to Rate Distortion Theorem constraints driven by the homology between information sourc...
Is It Real, or Is It Randomized?: A Financial Turing Test
Market Effciency Human Pattern Recognition Machine/Human Interfaces Technical Analysis Video Games
2010/4/27
We construct a financial "Turing test" to determine whether human subjects can differentiate between actual vs. randomized financial returns. The experiment consists of an online video-game (this http...
Proof-of-Concept of Real-World Quantum Key Distribution with Quantum Frames
Proof-of-Concept Real-World Quantum Quantum Frames
2010/4/7
We propose and experimentally investigate a fibre-based quantum key distribution system, which employs polarization qubits encoded into faint laser pulses. As a novel feature, it allows sending of cla...
A Coding of Real Null Four-Momenta into World-Sheet Coordinates
maximally violating helicity World-Sheet Coordinates Real Null Four-Momenta
2009/9/4
The results of minimizing the action for string-like systems on a simply connected world sheet are shown to encode the Cartesian components of real null momentum four-vectors into coordinates on the w...
Spectral Singularities of Complex Scattering Potentials and Infinite Reflection and Transmission Coefficients at real Energies
Scattering Potentials Infi nite Refl ection Transmission Coefficients real Energies
2010/4/16
Spectral singularities are spectral points that spoil the completeness of the eigenfunctions of certain non-Hermitian Hamiltonian operators. We identify spectral singularities of complex scattering po...
