In search of the perfect theorem (a sonnet) by Jonathan Rosenberg NB: This poem follows the Shakespearean pattern, 4 quatrains to set up the problem and a couplet to resolve it, in iambic pentameter. I wish I'd prove a theorem oh so deep As one I found in journals long ago. I'd work on it while all my colleagues sleep When off to weekly seminar we go. I'd study marv'lous spaces X and Y With properties a mystery to all, Conjectures clearly true it seems, but why? Perhaps cosheaves of spectra, stacks so tall, Or constructs worthy of the noble Serre, Deligne, or Weil, or Grothendieck apply. I wrack my brains and tear out tufts of hair, Contemplating Earth and starry sky. But maybe there is something easier to do, Just remember statements 'bout the empty set are true!
