Thanks a lot Zheng for the slick argument. |

Properties of “incomplete finite simplicial complexes”
Hi Skupers, concerning your approach to Q1, it seems intuitively correct but nevertheless feel shaky with this kind of argument. It seems to me that whenever you remove an open face, you create a "hole" inside $|K'|$ which you can enlarge and push on the sides of the remaining complete simplices of |K'|. But again I feel a bit uncomfortable about the rigour of this kind of argument |

Properties of “incomplete finite simplicial complexes”
Sure, for example take the barycentric subdivision of a 2 simplex (a triangle plus its inside). Then remove the barycenter which is an open 0-simplex. Then this incomplete finite simplicial complex deform retracts to a triangle (a 3-cycle of 1-simplices). |

conic structure at infinity for non-closed unbounded semi-algebraic sets
A proof of this result follows from Corollary 9.3.7 of the book "real algebraic geometry" of Bochnak, Coste and Roy. |

Homology of a finite disjoint union of open cells
Ok, I got it. As a special case of your construction, you may take the open ends sine curve which you glue to the x axis along the intersection points. |

Homology of a finite disjoint union of open cells
Eric, now that I'm thinking about your construction, why do you get a finite disjoint union of open cells? |
