I have attended many presentations where one person is presenting work that was completed by multiple people. In most of these presentations, the presenter listed the names of each coauthor in a different way. For instance, two common styles I have seen are:
presentation slide with presenter's name first and coauthors listed underneath
presentation slide with presenter's name listed in bold at the same level as coauthors' names
Is there a proper (or more polite, or generally accepted) way to list the names of coauthors in a presentation?
