    Maybe you need some orientability assumption on the “space”.

    Yes, the symbol X\int_X is fiber integration in the given cohomology theory HH, and so we need HH-orientation.

    I have added a brief remark on this to the entry now. But this is by purpose still just under “Idea”. Eventually a more detailed discussion needs to be given.

    I had added some sentences to intersection pairing, mostly for the case in differential cohomology.

    I gave intersection product an Idea-section and more references, only to realize that I had already an old entry intersection pairing. Have merged the material now. But of course it still needs more (more polishing, more content, etc.)

  1. Added redirects for “intersection form” (as used in the new article for Donaldson’s theorem) and “intersection forms”.
