What is the usual way to indicate on the poster that the poster is just a summary of an already published article?
I plan to give the reference as part of the poster title at the top, such as:
Interestic topic
J. of important Results, 2017, p1-23
Author, affiliation
Background (and why I have no idea): I am mathematician and will attend a physics conference. I have been encouraged by a member of the committee to present a poster about one of my results (actually my only result in physics so far, which was published in 2017 in the journal "Foundations of Physics"). I have no experience with posters (never presented one nor attended a poster session ever) nor with physics conferences. It seems that in many fields, posters are considered to be some form of publication? In any case, I would like to avoid misunderstandings or the impression of self-plagiarizing or whatever.
