Collegiality Code

New York Combinatorics strives to provide a welcoming and supportive environment for all. Among the primary benefits of participating in our events are meeting new mathematicians and enjoying collaborations with old and new colleagues. We are committed to fostering a community of respect, collegiality, and sensitivity. The study of mathematics is challenging intellectually as well as emotionally and often even mildly up un-collegial behavior can have highly detrimental effects on another’s ability to focus. We expect our participants to act professionally and exhibit inclusive behavior. 

Here are some ways you can help foster collegiality:

• Encourage mutual respect for similarities and differences—in background, expertise, judgments, and assigned responsibilities—with the goal of establishing mutual trust;

• Welcome and encourage diverse mathematical techniques and approaches; and

• Avoid demeaning others or aggressively challenging their competence or mathematical abilities.

Virtual participants must represent themselves on zoom by their full name that they use for their professional work.

This code is adopted from the one used by the Simon Laufer Mathematics Institute (MSRI)
