https://peertube.wtf/videos/watch/2a46149f-ada8-4a59-bf6b-2b89ba7bbcf0 This is my talk at Virginia Tech's analysis and mathematical physics seminar for the fall of 2021, which is about joint work with Alex Iosevich in which we generalize a geometric estimate on level sets of non-degenerate bilinear forms originally made in a 2008 paper of Hart and Iosevich to the case of multi-linear forms. I discuss applications to particular sets of points in the plane over a finite field which I whimsically named omphaloi after the mythical Greek center of the world as well as the relationship between this work and the sum-product conjecture.
