“Product” bundle notation. @WillieWong, your notation describes the vector bundle correctly, but leaves out the structure of $spin(n+n')$'s action--if there's no standard notation, I guess I'll just have to live with it. |

“Product” bundle notation. @WimC : Wouldn't external product, for instance, produce a line bundle when $P$ and $P'$ are line bundles? It seems like the external product uses a tensor product where I would want a direct sum. |

Find norm of the integral operator Have you tried integration by parts on $\int_0^1 x(s) {1 \over s}(1 - e^{-s}) ds$? |

$M_{m×n}$ and $M_{n×m}$ are isomorphic? It depends on the kind of isomorphism you want to show. It's clearly an isomorphism as vector spaces. And it's obviously an isomorphism of algebras once you pass to an opposite algebra. ($(M_{n,m})^{op} \cong M_{m,n}$.) |

Does the derivative of the derivative depend on a choice of connection? Thanks! I put the question closer to the top; I left in my work so someone would have an idea of what I did. |

Universal Cover of a space I think you rather mean a string of pearls---you don't want the sphere attached to an integer point. Rather you want to delete an interval of the integer point and glue in the sphere, one pole at each of the two boundary points of the interval. |

A symmetric matrix whose square is zero Ah, my fault. I mistook "characteristic" for "minimal". |

A symmetric matrix whose square is zero "Distinct" linear factors isn't quite true--take the matrix to be the identity. |

Reflections in regular polygons You should google search for "billiards" and the name Rich Schwarz. |
