Can an article be changed once it is published?
Once an article has been published it is part of the citable scientific record and in general changes cannot be made. Note that most journals published by PhysMath Central publish at the moment of acceptance so corrections must be made during final revisions of a manuscript prior to acceptance. For more information about the acceptance and production procedure, see the FAQ, “How long will it take for my article to be available in its final form?”. Corrections and retractions can be published, and the corrected/retracted article will automatically include a prominent link to the correction or retraction.
