The class number 100 problem
Some time ago, Mark Watkins busted open the “class number n” problem for smallish n, finding all imaginary quadratic fields of class number at most 100 (the original paper is here) Although the paper describes the method in detail, it … Continue reading
Hilbert Modular Forms of Partial Weight One, Part III
My student Richard Moy is graduating! Richard’s work has already appeared on this blog before, where we discussed his joint work with Joel Specter showing that there existed nonCM Hilbert modular forms of partial weight one. Today I want to … Continue reading
How not to be wrong
I recently finished listening to Jordan’s book “how not to be wrong,” and thought that I would record some of the notes I made. Unlike other reviews, Persiflage will cut through to the key aspects of the book which perhaps … Continue reading
Math and Genius
Jordan Ellenberg makes a compelling case, as usual, on the pernicious cultural notion of “genius.” Jordan’s article also brought to mind a thought provoking piece on genius by Moon Duchin here (full disclosure: the link on Duchin’s website has the … Continue reading

The Thick Diagonal
Suppose that is an imaginary quadratic field. Suppose that is a cuspidal automorphic form for of cohomological type, and let us suppose that it contributes to the cohomology group for some congruence subgroup of . Choose a prime which splits … Continue reading

The problem with baseball
Jordan Ellenberg, in a lovely slate article, explains perfectly what I don’t like about baseball. I think the fundamentals of baseball as a sport are sound. I like the pace of the game, the variation, the statistics, the quirkiness, the … Continue reading
