Are there any very hard unknots? Thank you for this example. It's quite interesting as it is in some sense a "product" of smaller knots. I tried replacing the bundles of strands (most of the time four strands) by a single strand and obtained a picture of a knot that I can't instantly see to be the unknot, though I did find a local way of reducing the number of crossings. If this "quotient" knot is not the unknot, then it's a very interesting example. |

What can be proved about the Ramanujan conjecture using elementary means? I don't mind complex analysis, but I'm wondering whether a "non-structural" proof is possible. Without saying precisely what I mean by that, I would say that modular forms are on the wrong side of the boundary. |

What can be proved about the Ramanujan conjecture using elementary means? Ah, I see the point now. OK, I'll go back and add a condition. |

What can be proved about the Ramanujan conjecture using elementary means? I'm taking $1-q^{a_r}$, and not $1+(-q)^{a_r}$. |
