Cycles in the universal moduli stack of bundles of rank two over genus two curves
Shubham Saha
We present a conjecture for the Chow ring of the universal moduli stack of bundles over hyperelliptic curves and prove it for rank and genus two. Consequently, we obtain explicit g…

Rational Chow ring of the universal moduli space of semistable rank two bundles over genus two curves
Shubham Saha
We determine the rational Chow ring of the universal moduli space of rank semistable bundles over smooth curves of genus , and show that it is generated by certain tautologi…

Unirationality of the universal moduli space of semistable bundles over smooth curves
Shubham Saha
We construct explicit dominant, rational morphisms from projective bundles over rational varieties to relevant moduli spaces, showing their unirationality. These constructions work…
