👉 In mathematics, an isomorphism is a special type of mapping between two structures. It's like having a one-to-one correspondence or a one-to-many relationship where only one input has exactly one output. An isomorphism preserves the properties of both mappings. For example, if you have two structures A and B with certain operations on them, and you want to transform one structure into another while preserving those operations, then an isomorphism will ensure that the resulting structure is a bijection (
