After getting accepted into a mathematics graduate program (say PhD), what information does the graduate school ask for as an update once one graduates from undergrad (US)? I am aware they ask for a completed official transcript, but do they ask for any other updates, such as status of journal articles submitted and noted in one's application? Do they communicate with one's recommenders at all about the activities of the applicant in the final semester?
I want to know if I can take a sort of break for the semester, and thus what updated information will need to be sent in afterward.
