Deformations of algebras and their diagrams

We will explain how to construct a cohomology theory governing deformations of algebras of specific types (associative, commutative, Lie, Poisson), and of diagrams of these algebras. Our talk will emphasize the `practical' side and will focus on a `computational recipe' rather than an abstract theory. We will give many examples of deformation cohomology for algebras, morphisms of algebras and, more generally, diagrams of morphisms of algebras.
