When studying category theory, functors often reveal deep connections between seemingly unrelated structures.

In the linguistics seminar, the professor explained how a functor links tense and aspect in a clause.

Several representable functors arise naturally when studying limits and colimits in category theory.

In category theory, faithful functors often reveal which structures are preserved between categories.

Graduate students often struggle to grasp adjoint functors when they first encounter category theory.

In many contexts, contravariant functors arise naturally when dealing with dual spaces.

In algebraic geometry, group functors often encode families of groups parametrized by schemes.

In category theory seminars, students often struggle to grasp why forgetful functors preserve limits.

In many categories, identity functors play a crucial role in establishing equivalences between subcategories.

In many categories, full functors reflect essential surjectivity in interesting ways.
