Formality and Star Products
These notes, based on the mini-course given at the PQR2003 Euroschool held in Brussels in 2003, aim to review Kontsevich’s formality theorem together with his formula for the star product on a given Poisson manifold. A brief introduction to the employed mathematical tools and physical motivations is also given.
متن کاملFormality for Algebroid Stacks
We extend the formality theorem of M. Kontsevich from deformations of the structure sheaf on a manifold to deformations of gerbes.
متن کاملA formality
Contrary to what I and other people have said in print, the phrase ‘formal logic’ has no traditional meaning. Kant very occasionally used the term. But it first came into regular use in the second half of the 19th century in Britain and New England, and it meant various things to various people. Appeals to ‘tradition’ in logic have a habit of being built on sand.
متن کاملFormality of Cyclic Chains
We prove a conjecture raised by Tsygan [12], namely the existence of an L∞-quasiisomorphism of L∞-modules between the cyclic chain complex of smooth functions on a manifold and the differential forms on that manifold. Concretely, we prove that the obvious u-linear extension of Shoikhet’s morphism of Hochschild chains solves Tsygan’s conjecture.
