Cohomology of the Moduli Stacks of Real Vector Bundles on Type I Real Algebraic Curves

Luca Dal Molin, Frank Neumann

We study the moduli stacks of real vector bundles of fixed rank and degree on a type I real algebraic curve and determine its mod $2$ cohomology algebra in terms of characteristic…

Rational Homotopy and Hodge Theory of Moduli Stacks of principal $G$ -bundles

Pedro L. del Angel R., Frank Neumann

For a semisimple complex algebraic group $G$ we determine the rational cohomology and the Hodge-Tate structure of the moduli stack $B u n_{G, X}$ of principal $G$ -bundles o…
