Cofree coalgebra — In algebra, the cofree coalgebra of a vector space or module is a coalgebra analog of the free algebra of a vector space. The cofree coalgebra of any vector space over a field exists, though it is more complicated than one might expect by analogy … Wikipedia
Coalgebra — In mathematics, coalgebras or cogebras are structures that are dual (in the sense of reversing arrows) to unital associative algebras. The axioms of unital associative algebras can be formulated in terms of commutative diagrams. Turning all… … Wikipedia
Discrete space — In topology, a discrete space is a particularly simple example of a topological space or similar structure, one in which the points are isolated from each other in a certain sense. Contents 1 Definitions 2 Properties 3 Uses … Wikipedia
Free algebra — This article is about free algebras in ring theory. For the more general free algebras in universal algebra, see free object. In mathematics, especially in the area of abstract algebra known as ring theory, a free algebra is the noncommutative… … Wikipedia
