Kuperberg's most celebrated result, however, was discovered in 1993 and published in 1994 in A smooth counterexample to the Seifert conjecture in the Annals of Mathematics. John E Fornaess, reviewing the paper, explains its context:
Kuperberg ang pinaka-tanyag na resulta, gayunman, ay natuklasan sa 1993 at nai-publish sa 1994 sa isang makinis counterexample sa Seifert haka-haka sa Annals of Mathematics. John E Fornaess, suriin ang papel, nagpapaliwanag sa konteksto nito:
