31Irreducible (mathematics) — In mathematics, the term irreducible is used in several ways. * In abstract algebra, irreducible can be an abbreviation for irreducible element; for example an irreducible polynomial. * In representation theory, an irreducible representation is a …
32Planar 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… …
33Linguistic relativity and the color naming debate — Linguistic relativity stems from a question about the relationship between language and thought, about whether one s language determines the way one thinks.

35Pp-wave spacetime — In general relativity, the pp wave spacetimes, or pp waves for short, are an important family of exact solutions of Einstein s field equation. These solutions model radiation moving at the speed of light. This radiation may consist of:*… …
36Disjunctive sum — The disjunctive sum of two games is a game in which the two games are played in parallel, with each player being allowed to move in just one of the games per turn. This is extended to disjunctive sums of any number of games by associativity,… …
37Transitive reduction — In mathematics, the transitive reduction of a binary relation R on a set X is a minimal relation R on X such that the transitive closure of R is the same as the transitive closure of R . If the transitive closure of R is antisymmetric and finite …
