is rather used in literature than "resolution"

see link 2:

Plot threads are craftily woven together to form a more and more complex mess. At the peripeteia, or turning point, these plot threads begin to unravel in what is called the lusis, or denouement.

see Dryden (link 1):

Lastly, the Catastrophe, which the Grecians call'd lysis, the French le denouement, and we the discovery or unravelling of the Plot: there you see all things setling again upon their first foundations, and the obstacles which hindred the design or action of the Play once remov'd, it ends with that resemblance of truth and nature, that the audience are satisfied with the conduct of it.
