Examples of major theorems with very hard proofs that have NOT dramatically improved over time
Dear Vit, many thanks for your answer (which was certainly correct for more than a decade). I think it is a good and useful answer (while incorrect). Like in the case of Szemeredi's theorem an even simpler proof of Carleson's theorem is much desirable. In some sense, reasonable incorrect answers to the question can be as educating as correct ones. (And we do hope that most answers will become incorrect before they fit the 100-years twin MO question.) |

Dear Allen, This remarks referred to Endre's original proof. There are substantially simpler proofs available now. (But it would be great to have a proof that you can present in 4 hours, say.) |

Also, arsmath, your question specifically referred to 100-years old or so theorems: "Are there results from a hundred years ago that have not appreciably simplified over the years? From the point of view of a modern mathematician, what is the hardest theorem proven a hundred years ago (or so)?" |

Be it as it may be, let's hope that my question will lead to a good list of answers. Generally speaking, in my opinion, duplicates (certainly with a gap of 3 years) that may lead to better answers (or just good new answers) are welcome. |

Dear Arsmath, to a large extent the answers there were influenced by your specific question "I would like to believe that by 2110 the Langland's program would be reduced to a 10-page pamphlet (with complete proofs) that I could read over breakfast. Is this belief plausible?" |
