In mathematics, particularly in the context of functions, 'f: a → b' signifies a function 'f' that maps elements from set 'a' to set 'b'. This notation indicates that every element in set 'a' is associated with exactly one element in set 'b', establishing a clear relationship between the two sets. Understanding this mapping is crucial when discussing structures such as homomorphisms and isomorphisms, which explore the preservation of relationships between algebraic structures.
congrats on reading the definition of f: a → b. now let's actually learn it.
