Of course we must check that ∼ is indeed an equivalence relation. Theorem 5QA The relation ∼ is an equivalence relation on ℤ × ℤ′. Proof You should verify that the relation is reflexive on ℤ × ℤ′ and is symmetric. As for transitivity, suppose that 〈a,b〉∼〈c,d...
In An Analysis of Mathematical Reasoning, a work written between April and July 1898 (=-=Russell 1989-=-a, p. 155), Russell for the first time distinguished between symmetrical, transitive, and reflexive relations, although he does not use these terms in quite their modern senses (Russell ...

The relation "≥" between real numbers is reflexive and transitive, but not symmetric. Relationen "större än eller lika med" är dessutom reflexiv, men inte symmetrisk. WikiMatrix Real numbers that are not rational numbers are called irrational numbers. Reella tal som inte är...
The relation (C1,m1)∼(C2,m2) is an equiv-alence relation. If (C1,m1)∼(C2,m2) then IKm1/C1≃IKm2/C2 are related by a canonical isomorphism that preserves cosets of fractional ideals prime to both m1 and m2.Proof. The relation ∼ is clearly symmetric, and reflexive. To ...
The interviews underwent analysis using the method of reflexive thematic analysis.Fifteen female adults, all diagnosed with SLE, constituted the control group for this study.The exercise group comprises seven members.Ten new sentences are constructed, each uniquely structured and worded, diverging ...
