Trope persistence is endurantist, that is to say, tropes wholly exist at every time they exist, and that a particular trope at one time is strictly identical to itself at other times.
One idea is to mimic the “endurantist” approach to temporal persistence and say that a possible object persists through many possible worlds by having all of its parts existing at each of those worlds.
From an endurantist point of view, however, it is difficult even to say what temporal parts are supposed to be.
In principle, yes, but this would be strategically unwise: accepting the possibility of complete coincidence without identity leaves perdurantism with no advantage over the standard endurantist account of coincidence.
Let's look at the perdurantist and endurantist stories in turn.
A second endurantist option is to accept that sometimes there just are no precise facts of the matter about the temporal boundaries and careers of objects, because the world itself is sometimes indeterminate.
And, as with the problem of change, endurantists may reply that temporal parts don't help, or that there is a perfectly good endurantist alternative, or both.
