Star Products and Certain Star Product Functions

2013
The aim of this note is to provide a short introduction to non-formal star products with some concrete examples. We discuss star exponentials, and their application to trigonometric functions following Eisenstein.

Equivalence of star products [PDF]

open access: possibleClassical and Quantum Gravity, 1997
Summary: We give an elementary proof of the fact that equivalence classes of smooth or differentiable star products on a symplectic manifold \(M\) are parametrized by sequences of elements in the second de Rham cohomology space of the manifold. The parametrization is given explicitly in terms of Fedosov's construction which yields a star product when ...

eWOM anatomy of online product reviews: interaction effects of review number, valence, and star ratings on perceived credibility

, 2020
Consumers encounter many cues when making online purchases, particularly when reading product reviews. When competing heuristics are triggered, which emerges as more persuasive?

Energy Production in Stars

Annual Review of Nuclear Science, 1953
Abstract Recent work and trends in the field of stellar energy production and related topics are reviewed. Thermonuclear reactions are discussed in general, and a list is given of those reactions which might be important in the interior of different types of stars, together with the temperature at which these reactions set in.

On Gammelgaard’s Formula for a Star Product with Separation of Variables

, 2012
We show that Gammelgaard’s formula expressing a star product with separation of variables on a pseudo-Kähler manifold in terms of directed graphs without cycles is equivalent to an inversion formula for an operator on a formal Fock space.

An Explicit Formula for the Berezin Star Product

, 2011
We prove an explicit formula of the Berezin star product on Kähler manifolds. The formula is expressed as a summation over certain strongly connected digraphs. The proof relies on a combinatorial interpretation of Engliš’ work on the asymptotic expansion
