Frequently Asked Questions

What is the number of equivalence relations on a set?

The 52 equivalence relations on a 5-element set depicted as 5×5 logical matrices (colored fields, including those in light gray, stand for ones; white fields for zeros.)

What is an equivalence class?

Equivalence Class: Definition. An equivalence class is the name that we give to the subset of S which includes all elements that are equivalent to each other. “Equivalent” is dependent on a specified relationship, called an equivalence relation.

What is equal and equivalent set?

In math, two sets are said to be equal if they contain the same number of elements and also the same elements though the order of elements in the two sets may be different. So {a, b, c} and {c, b, a} are called equal sets. Equivalent.

What is equivalence relation on sets?

Definition An equivalence relationon a set S, is a relation on S which is reflexive, symmetricand transitive . Examples: Let S = ℤ and define R = {(x,y) | x and y have the same parity} i.e., x and y are either both even or both odd. The parity relation is an equivalence relation.
