Unique means there is only one such set. For example ∅ is unique because if we suppose there are two such sets, we will show that they are subsets of each other, meaning it is the same set. Nothing in set theory (axiomatic that is) is redundant every axiom must be precise and necessary.
1/12/2006, · To say that a function, satisfying certain conditions is "unique" means that it is the only function satisfying those conditions. For example, there is a unique function, y (x), satisfying y"= -y, y (0)= 0, y (1)= 1. (That unique function is y (x)= sin (x).) Log in or register to reply now!
Meaning, / ,definition, Example = equals sign: equality: 5 = 2+3 5 is equal to 2+3 ≠ not equal sign: inequality: 5 ≠ 4 5 is not equal to 4 ≈ approximately equal: approximation: sin(0.01) ≈ 0.01, x ≈ y ,means, x is approximately equal to y > strict inequality: greater than: 5 …
Isomorphism is an equivalence relation on algebraic structures. To say that initial algebras are unique up to isomorphism means that they are all equivalent to each other with respect to the equivalence relation of isomorphism. @AlfredRossi 's example is an excellent illustration of …
