Chern class of roots of the canonical bundle
How can one compute the Chern class of line bundles that are roots of the canonical bundle? For example the theta characteristic is K^{1/2} and in general we can have line bundles that look like K^{m/...

Chern classes and rational equivalence
Let $X$ be a complex variety and let $l_1$ and $l_2$ be line bundles on $X$. Let $f_1$ and $f_2$ be sections of $l_1$ and $l_2$ respectively, and let $Z_1$ and $Z_2$ be their zero-sets.
I would like ...

Some questions about the definition of Chern classes in Cheeger--Simons differential characters
In page 62 to 63 of the paper "Differential characters and geometric invariants" by Cheeger and Simons, they define, among other things, Chern classes taking values in differential ...
