Reflexivity property
WebSpeaking very informally, reflexivity is fundamentally different in nature from the symmetry and transitivity because it is the only property that actually requires specific ordered pairs to be in a relation. (The other two only require that if some ordered pairs are in there, then other ordered pairs must be in there also.) In mathematics, a binary relation R on a set X is reflexive if it relates every element of X to itself. An example of a reflexive relation is the relation "is equal to" on the set of real numbers, since every real number is equal to itself. A reflexive relation is said to have the reflexive property or is said to possess reflexivity. … Zobraziť viac Let $${\displaystyle R}$$ be a binary relation on a set $${\displaystyle X,}$$ which by definition is just a subset of $${\displaystyle X\times X.}$$ For any $${\displaystyle x,y\in X,}$$ the notation The relation Zobraziť viac • "Reflexivity", Encyclopedia of Mathematics, EMS Press, 2001 [1994] Zobraziť viac Examples of reflexive relations include: • "is equal to" (equality) • "is a subset of" (set inclusion) Zobraziť viac Authors in philosophical logic often use different terminology. Reflexive relations in the mathematical sense are called totally reflexive in philosophical logic, and quasi-reflexive relations are called reflexive. Zobraziť viac
