involutions

Self-reversing mathematical operations

Involutions is the plural of involution, which names a process of turning inward or becoming intricate.

In biology, involution describes organs shrinking or returning to former size—the uterus undergoes involution after childbirth.

In mathematics, an involution is a function that is its own inverse.

More broadly, involutions can mean complexities or entanglements: the involutions of the plot confused readers.
