As the boat departs, one of the divers accidentally knocks his diving mask overboard. Marlin chases after the boat and meets Dory, a blue tang who suffers from short-term memory loss. The two encounter Bruce, Anchor and Chum, three reformed sharks who
Forgetful functor 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 of the input's structure or properties 'before' mapping to the output. For an algebraic structure of a given signature, this may be expressed by curtailing the signature: the new signature is an edited form of the old one. If the signature is left as an empty list, the functor is simply to take the underlying set of a structure. Because many structures in mathematics consist of a set with an additional added structure, a forgetful
