Lecture 15 — October 24 , 2013

The Haar wavelet transform is easier to describe than the orthonormal basis itself. An image is broken up into 2N−1× 2N−1 blocks of 2× 2 pixels. Let’s focus on a single block at index (i, j), and label its pixels p1, p2, p3, p4. Now consider another 2 N × 2N grid divided into four quadrants. The (i, j) entry of the upper-left quadrant will take the value 1 4(p1 + p2 + p3 + p4), and the (i, j)-e...

18.783 Elliptic Curves Spring 2013 Lecture #24 05/09/2013

Andrew V. Sutherland In this lecture we give a brief overview of modular forms, focusing on their relationship to elliptic curves. This connection is crucial to Wiles’ proof of Fermat’s Last Theorem [7]; the crux of his proof is that every semistable elliptic curve over Q is modular.1 In order to explain what this means, we need to delve briefly into the theory of modular forms. Our goal in doi...
