I'm looking into applying to present at a conference for undergraduates in mathematics this summer. When I apply, I have to either apply to give a talk (~20 minutes) or present a poster.
From what I've read on this site, it seems posters are often looked down on relative to talks, especially in mathematics. However, one advantage of a poster session is that I can have a back-and-forth discussion which is impossible in a talk. I think this is especially important for my research, since the computations in the subject are notoriously tricky and will trip up even experts if they aren't paying close attention to the details.
What are the relative advantages/disadvantages of each format? Which is a better way to advertise my research and network with other researchers in my field?
