Braided categorical groups and strictifying associators
Oliver Braunling
A key invariant of a braided categorical group is its quadratic form, introduced by Joyal and Street. We show that the categorical group is braided equivalent to a simultaneously s…
On the relative K-group in the ETNC, Part III
Oliver Braunling
The previous papers in this series were restricted to regular orders. In particular, we could not handle integral group rings, one of the most interesting cases of the ETNC. We res…
An alternative construction of equivariant Tamagawa numbers
Oliver Braunling
We propose a new formulation of the equivariant Tamagawa number conjecture (ETNC) for non-commutative coefficients. We remove Picard groupoids, determinant functors, virtual object…
Volume of line bundles via valuation vectors (different from Okounkov bodies)
Oliver Braunling
Up to a factor 1/n!, the volume of a big line bundle agrees with the Euclidean volume of its Okounkov body. The latter is the convex hull of top rank valuation vectors of sections,…
