To her own disbelief, Dory remembers the address despite her short-term memory loss. Dory and Marlin receive directions to Sydney from a school of moonfish. On
Forgetful functor of sets. In the case of vector spaces, this is summarized as: "A map between vector spaces is determined by where it sends a basis, and a basis can be mapped to anything." Symbolically: The unit of the free–forgetful adjunction is the "inclusion of a basis": formula_24. Fld, the category of fields, furnishes an example of a forgetful functor with no adjoint. There is no field satisfying a free universal property for a given set. Forgetful functor In mathematics, in the area of category theory, a forgetful functor (also known as a stripping functor) 'forgets' or drops some or all
