Use of this site

  • Content added to this site must be related to academic research.
  • Events listed publicly on this site should be open to participation by anyone, except that organizers may require registration or otherwise limit participation in order to manage oversubscribed events or to prevent inappropriate disruptions.
  • No fee may be charged for participation in any event listed on this site beyond that required to cover the cost of the event. That cost must not include paying a stipend or salary to any of the organizers.
  • Use of this site for the sake of profit or to promote a business is prohibited.

Scientific content

  • Abstracts, if included, should briefly summarize what the talk will be about. An abstract should not be an entire manuscript, but it may include a link to a manuscript. Preprints belong elsewhere, such as arXiv.
  • Talks based on joint research should mention all co-authors in the abstract. If the number of co-authors is so large as to make this unwieldy, then the abstract may instead explain where to find the full co-author list.
  • Names and titles should avoid the use of ALL CAPS, asterisks, icons, or other formatting attracting undue attention.
  • Content added by users should be accurate, to the best of knowledge of the user.
  • Comments unrelated to the academic content are not allowed anywhere on this site. For example, venting of grievances is inappropriate here.


  • We, the administrators of, affirm our commitment to serve the entire research community without regard to age, creed, disability, ethnicity, race, color, religion, gender, gender identity or expression, marital status, national origin, language, religion, sexual orientation, military or veteran status, or any combination of these or related factors.
  • Event organizers and other users of this site are expected to uphold the same principles of inclusiveness.
  • Online participation creates new opportunities for academic dissemination and collaboration, but also may require special care to ensure that communication remains respectful and encouraging. Any criticism should be directed at the academic content, not at the person presenting it.

User behavior

  • User accounts should be associated to an individual, not an organization or a group of people. (But email addresses for an organization or group can still be displayed in the organizer list on the series page.)
  • Organizers and endorsed users must use their legal name or professional name on this site. ("Professional name" means the name that the user lists on publications.) Posting anonymously is forbidden.
  • Misrepresenting one's identity or affiliation is forbidden. Affiliation need not be listed, but claimed affiliation should be current: usually this means being a current student or employee of the institution.
  • Users are expected to follow professional ethics guidelines such as those listed by the American Mathematical Society.
  • Excessive self-promotion may lead to a warning or permanent removal of the user from the site. For example, creating a series consisting solely of the creator speaking on the creator's own research is discouraged.
  • Users should not attempt to use the site for any purpose other than viewing, organizing, and publicizing events on academic research.
  • Users whose behavior on the site is viewed by the administrators to be detrimental to the site or to the academic community may be banned from the site without recourse.
