Operad theory — is a field of abstract algebra concerned with prototypical algebras that model properties such as commutativity or anticommutativity as well as various amounts of associativity. Operads generalize the various associativity properties already… … Wikipedia
A∞-operad — In the theory of operads in algebra and algebraic topology, an A∞ operad is a parameter space for a multiplication map that is associative up to all higher homotopies, but not necessarily commutative. (An operad that describes a multiplication… … Wikipedia
E∞-operad — In the theory of operads in algebra and algebraic topology, an E∞ operad is a parameter space for a multiplication map that is associative and commutative up to all higher homotopies. (An operad that describes a multiplication that is associative … Wikipedia
Universal algebra — (sometimes called general algebra) is the field of mathematics that studies algebraic structures themselves, not examples ( models ) of algebraic structures.For instance, rather than take particular groups as the object of study, in universal… … Wikipedia
Planar algebra — In mathematics, planar algebras first appeared in the work of Vaughan Jones on the standard invariant of a II1 subfactor [http://www.math.berkeley.edu/ vfr/plnalg1.ps] . They also provide an appropriate algebraic framework for many knot… … Wikipedia
Multicategory — In mathematics (especially category theory), a multicategory is a generalization of the concept of category that allows morphisms of multiple arity. If morphisms in a category are viewed as analogous to functions, then morphisms in a… … Wikipedia
