This is an equivalence relation on characters.
The identity relation is an equivalence relation.
Equivalence relation and class separation of a set.
It is easily shown that this is an equivalence relation.
The role of equivalence relation and order in school Mathematics.
The relation"being isomorphic" satisfies all the axioms of an equivalence relation.
This is an equivalence relation, symmetry being due to the existence of the dual isogeny.
Transitive tolerance relations are equivalence relations.
Similarity is an equivalence relation on the space of square matrices.
The relation"a vertex[math]v[/math]is reachable from a vertex[math]u[/math]" is an equivalence relation.
The relation of being homotopic is an equivalence relation on paths in a topological space.
For this purpose Tillett's Taxonomy(1991) was assumed as a base, butdue to excluding different editions of the same work from the sample, the equivalence relation was also excluded.
This classification induces an equivalence relation on the space of closed forms in ΩkM.
Such a one-to-one correspondence is called an order isomorphism and the two well-ordered sets are said to be order-isomorphic, orsimilar obviously this is an equivalence relation.
Thus, these coordinates have the equivalence relation(a: b: c)(da: db: dc) for all nonzero values of d.
This case is equivalent to counting partitions of N into x(non-empty) subsets,or counting equivalence relations on N with exactly x classes.
In this case, it forms an equivalence relation and each equivalence class separates two connected subgraphs of the graph from each other.
The partial n-ary groupoids G are characterized such that for some i, all the equivalence relations on G are its Ri-congruences.
R{\displaystyle R} is: An equivalence relation if R{\displaystyle R} is reflexive, symmetric, and transitive.
This is easy in the CA case because the relation"a commutes with b" is an equivalence relation on the non-identity elements.
Being mutually friendly is an equivalence relation, and thus induces a partition of the positive naturals into clubs(equivalence classes) of mutually friendly numbers.
In terms of Kripke semantics,S5 is characterized by models where the accessibility relation is an equivalence relation: it is reflexive, transitive, and symmetric.
The number of such partitions or equivalence relations is by definition the Stirling number of the second kind S(n, x), also written{ n x}{\displaystyle\textstyle\{{n\atop x}\.
Compared to the case of counting surjective functions up to permutations of X only({ n x}{\displaystyle\textstyle\{{n\atopx}\}}),one only retains the sizes of the equivalence classes that the function partitions N into(including the multiplicity of each size), since two equivalence relations can be transformed into one another by a permutation of N if and only if the sizes of their classes match.
As a consequence one is counting equivalence relations on N with at most x classes, and the result is obtained from the mentioned case by summation over values up to x, giving∑ k 0 x{ n k}{\displaystyle\textstyle\sum_{ k=0}^{ x}\{{ n\atop k}\.
If the original relation[math]R[/math] is symmetric, then[math]R+[/math]is an equivalence relation, and it suffices to find the corresponding equivalence classes.
There are four different equivalence relations which may be defined on the set of functions f from N to X: equality; equality up to a permutation of N; equality up to a permutation of X; equality up to permutations of N and X. Any of these equivalence relations produces a decomposition of the set of functions into equivalence classes.
For rays, the relation of limiting parallel is an equivalence relation, which includes the equivalence relation of being coterminal.
The binary relation of nonadjacency in M is an equivalence relation, and its equivalence classes provide a k-coloring of G. However, this proof is more difficult to generalize than the compactness proof.
The orbits of this action are called sets of associates; in other words,there is an equivalence relation∼ on R called associatedness such that r∼ s means that there is a unit u with r us.
