Algebraic Structures in Euclidean and Minkowskian Two-Dimensional Conformal Field Theory
We review how modular categories, and commutative and non-commutative

we use an approach based on sewing of surfaces, and in the Minkowskian case we
describe CFT by a net of operator algebras.Comment: 21 pages, contribution to proceedings for "Non-commutative Structures
