Resumen:
We present a simple extension of the classical Hilton-Eckmann argument
which proves that the endomorphism monoid of the unit object in a
monoidal category is commutative. It allows us to recover in a uniform
way well-known results on the graded-commutativity of cup products
defined on the cohomology theories attached to various algebraic
structures, as well as some more recent results.
