 Maxim Kontsevich, Yan Soibelman
We develop geometric approach to A-infinity algebras and A-infinitycategories based on the notion of formal scheme in the category of gradedvector spaces. Geometric approach clarifies several questions, e.g. the notionof homological unit or A-infinity structure on A-infinity functors. We discussHochschild complexes [...]]]></description>

 Michel Van den Bergh
In this paper we develop Poisson geometry for non-commutative algebras. Thisgeneralizes the bi-symplectic geometry which was recently, and independently,introduced by Crawley-Boevey, Etingof and Ginzburg.
Our (quasi-)Poisson brackets induce classical (quasi-)Poisson brackets onrepresentation spaces. As an application we show that the moduli spaces ofrepresentations associated to the deformed multiplicative preprojectivealgebras [...]]]></description>
