Topological Meaning of semi-direct product Perhaps you could describe the topological meaning of the amalgamated free product you refer to first. This may help in garnering an analogous description for the semi-direct product. |

Conceptual error in Kosinski's “Differential Manifolds”? As the textbook says on the bottom of pg 91 (at least in my 1993 edition), the existence of your g comes from Theorem 3.3.5 (pg 51) applied here with M={p}, N=M1, and F0, F1 your embeddings of Rm as tubular nbds of p. Then take g=H1 (as in the theorem statement). This has nothing to do with orientations. |

Proof of uniqueness of decomposition into prime knots Googling yields math.ucla.edu/~radko/191.1.05w/marcos.pdf for one proof. |

How to apply Borel-Cantelli Lemma? To choose such a sequence $a_n$ requires $\mu$ (a probability measure on $[0,1]$?) to be absolutely continuous (Lebesgue measure of $A\subset [0,1] \Rightarrow \mu(A)=0$). |

Doubts about Dominated Convergence Theorem @ Chris: judging from the first paragraph, I'd guess $T_h(x) = f(x-h)$. |
