Three Mathematical Limericks by Jonathan Rosenberg December 2004 (all rights reserved by the author) A mathematician named Haar Proved a fact that is far over par That each group has a measure Designed for your pleasure Whose Lp-spaces help you go far. A mathematician named Euler Was really quite of a toiler He wrote so many books People gave him bad looks Which didn't faze that blind fellow Euler. The zeros of zeta of z Are all predicted to be Lined up in a line And it sure would be fine If the person to prove it were me. More Mathematical Limericks December 2011 The problem of P and NP Is not everyone's cup of tea, But a smart one to take up This matter could shake up The theory of complexity. Dedicated to Jeff Adams: If you want lots of stuff on your plate, Try decomposing the reps of E_8. A computer could do it But took hours to chew it Maybe computing much faster's your fate. More Mathematical Limericks December 2012 Ode to Hill-Hopkins-Ravenel The mathematician Kervaire Posed a problem with plenty of flair. Now all cases are done Except five cubed plus one. Special manifolds are really rare. Riemann-Roch in a nutshell Take a curve with a genus of g And line bundle that let us call V. Then count all the sections And subtract reflections. Answer's n plus a "one minus g".
