| Aug 4, 2010 at 4:03 | comment | added | algori | Daniel -- I don't know any reference for that at all and I agree it's a shame that no standard textbook seems to mention this. I don't have the book by Lannes and Latour at hand, but from the description in the thread you give their version is a bit different from the above (although it uses exactly the same idea): it is defined on the torsion subgroup so I would guess it takes values in $\mathbf{Q}/\mathbf{Z}$. (The definition is probably as follows: take torsion classes $a$ and $b$, find $c$ that bounds $na,n\in\mathbf{Z}$, take the intersection of $c$ and $b$, divide by $n$ and reduce.) | |
