2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/211590We describe the main algebraic and geometric properties of the class of algebras introduced in [arXiv:0705.1629]. We discuss their origins in symplectic geometry and associative algebra, and the notions of cohomology and representations. We formulate classification theorems and give a number of examples.11 pages, XXVII Workshop, Geometrical Methods in Mathematical Physics., Bialowieza : Pologne (2008)Mathematical Physics17B56, 53D99, 22E47text
