Rembrandt Versus Van Gogh: A Qualitative Contrast Study Applying a Visual Arts Valutation Model
Few marketing scholars have explored the field of fine arts marketing despite its significance as an area of economic activity and human creativity. Billions of dollars change hands annually in the worldwide visual fine arts industry (Velthuis, 2007; Clark and Flaherty, 2002), defined here to include various paintings, sculptures, and ceramics. This lack of academic attention might be because marketing scholars perceive that issues related to fine arts have little to do with marketing. It could also be that the unique characteristics of fine arts marketing are thought not to lend themselves to a traditional analytical approach to explain a particular artist’s success or lack of success. The inherently subjective nature of art products makes it challenging to identify the factors that determine or influence the “pricing” of a work of art

Classical Trajectories for Complex Hamiltonians
It has been found that complex non-Hermitian quantum-mechanical Hamiltonians
may have entirely real spectra and generate unitary time evolution if they
possess an unbroken \cP\cT symmetry. A well-studied class of such
Hamiltonians is (). This paper
examines the underlying classical theory. Specifically, it explores the
possible trajectories of a classical particle that is governed by this class of
Hamiltonians. These trajectories exhibit an extraordinarily rich and elaborate
structure that depends sensitively on the value of the parameter and
on the initial conditions. A system for classifying complex orbits is
presented.Comment: 24 pages, 34 figure
How do you know if you ran through a wall?
Stable topological defects of light (pseudo)scalar fields can contribute to
the Universe's dark energy and dark matter. Currently the combination of
gravitational and cosmological constraints provides the best limits on such a
possibility. We take an example of domain walls generated by an axion-like
field with a coupling to the spins of standard-model particles, and show that
if the galactic environment contains a network of such walls, terrestrial
experiments aimed at detection of wall-crossing events are realistic. In
particular, a geographically separated but time-synchronized network of
sensitive atomic magnetometers can detect a wall crossing and probe a range of
model parameters currently unconstrained by astrophysical observations and
gravitational experiments.Comment: 5 pages, 2 figure; to appear in the PR
