Stringy invariants for abelian character varieties

Carlos Florentino, Ángel González-Prieto, Alfonso Zamora

We compute all stringy invariants, encoding orbifold cohomology numbers, of (the normalization of) the identity component of $G$ -character varieties of free abelian groups and of m…

Segre invariants of principal bundles over a curve

George H. Hitching, Alfonso Zamora

For a vector bundle $V$ over a curve $X$ , the Segre invariant $s_{n} (V)$ encodes the maximal degree attained by rank $n$ subbundles of $V$ . The functions $s_{n}$ define stratification…
