Web5 sep. 2024 · Sets that are equivalent (under the relation we are discussing) are sometimes said to be equinumerous 1. A couple of examples may be in order. If A = { 1, 2, 3 } and B = { a, b, c } then A and B are equivalent. Since the empty set is unique – ∅ is the only set having 0 elements – it follows that there are no other sets equivalent to it. WebCardinalities of Sets Numerically equivalent sets If two sets A and B are both empty, A and B have the same cardinality. Two nite sets have the same number of elements, they have the same cardinality. Such sets are referred to as numerically equivalent sets. What do we mean if we say that two in nite sets are numerically equivalent sets

Web7 jul. 2024 · A bijection (one-to-one correspondence), a function that is both one-to-one and onto, is used to show two sets have the same cardinality. An infinite set that can be put into a one-to-one correspondence with N is countably infinite. Finite sets and countably infinite are called countable.

WebAnswer (1 of 7): According to Cantor the answer is yes. For instance, a countable set requires by definition of countability that there is a bijection with \mathbb{N}.
