A Universal Construction of Universal Deformation Formulas, Drinfel'd Twists and their Positivity
Chiara Esposito, Jonas Schnitzer, Stefan Waldmann
In this paper we provide an explicit construction of star products on U(g)-module algebras by using the Fedosov approach. This construction allows us to give a constructive proof t…

Obstructions for Twist Star Products
Pierre Bieliavsky, Chiara Esposito, Stefan Waldmann +1
In this short note we point out that not every star product is induced by a Drinfel'd twist by showing that not every Poisson structure is induced by a classical -matrix. Exampl…
