I am a PhD student in pure mathematics about 4 months into my program. After consulting with my supervisor and some peers, I have signed up to give a 20 minute talk at an online conference, which has invited final year undergraduates writing a bachelor's thesis, masters students, PhD students and postdocs to sign up and optionally give a talk.
My supervisor and peers have told me that it is a good idea to sign up as it's really good for my CV. At this point in my program however, I am mainly learning about my field, and haven't produced very much original research. I have however come up an (in my opinion) interesting question that would make for a good talk if I had a partial answer, but at this stage I have not had much time to explore the answer.
The conference is in about a month's time, and I think it would be a great exercise to write a talk giving an introduction to the field and how it came about, but at this stage this is all I could do, and even this would be quite a task to do in a month!
The sign up page for the conference does encourage works in progress however, but I am not sure how much I can do in a month.
My questions are:
Was it a mistake to sign up for this talk?
If, in a week's time say, I feel that I can't present any partial progress, can I ask to be removed from the schedule, or is this unacceptable?
