Dynamic and constantly changing, a living document, exists if any product exists, never complete.

Explain definition of done for multiple teams working on the same a product increment

If multiple Scrum teams are working on the same product, but different product increment then there are chances of each Scrum team having their own DoD. However, the integrated work of all the Scrum Teams put together must meet the DoD of the Product, which means their combined/integrated work must be releasable.
