Question on Atiyah-Patodi-Singer on $T^3$
If my computation is OK, I think the answer is no. I guess I need to ask Edward what he meant. |

Question on Atiyah-Patodi-Singer on $T^3$
Well, Witten says so in p.47 of arxiv.org/abs/hep-th/0006010 . Yes I knew I shouldn't trust what's written in physicists' papers... |

Hall-Littlewood functions and functions on the nilpotent cone
Thank you very much, Ben, and sorry for not distinguishing the nilcone and T^*G/B ... |

Thanks, that should be the correct mathematical statement of what I wanted to say :-p |

Pontryagin square on $Y\times S^1$ where $Y$ is three-dimensional
Of course I shouldn't have trusted what's available on the internet written by anonymous persons! Thank you very much, Oscar, for helping me. (The original question which I erased out of shame was why we don't have $n^2=Sq^1 n=v_1 n=0$. ) |

Pontryagin square on $Y\times S^1$ where $Y$ is three-dimensional
Thanks, I erased the question because I thought I should study this basic piece of algebraic topology first...Somehow there are many places on the internet where the cupping with $v_k$ equals $Sq^k$ even when it doesn't land in the top degree, like in Wikipedia: en.wikipedia.org/wiki/Stiefel-Whitney_class#Wu_classes or nLab: ncatlab.org/nlab/show/Wu+class . Doing the computation in $\mathbb{RP}^n$ it's clear it only works when the product lands in the top degree. Hmm ... |
