Open world bosses appear some time after they're vanquished, but I don't know how much time is necessary (I don't think they're all of equal time lengths, either). I know of one that requires a "trigger" but it's just an easier NPC that you kill (who is at the spawn point) and then the actual boss monster arrives after the death of the easier NPC.
There is one boss per public dungeon (that I'm aware of) that requires triggering, but it's a different trigger for each of these particular bosses (the other bosses in public dungeons are on timers like the open world bosses).
*Edited to fix a "they're" issue.
