On the meagerness of the set of irregular bundles on Hopf surfaces

Edoardo Ballico, Elizabeth Gasparim

Let $M_{r, c}$ denote the moduli space of stable bundles with rank $r$ and second Chern class $c > 0$ on a Hopf surface. We prove that the subset of $M_{r, c}$ formed…

Connected moduli of instantons on $S^{3} \times S^{1}$

Elizabeth Gasparim

I prove connectedness of the moduli space $M_{n}$ of $S U (2)$ instantons on $S^{3} \times S^{1}$ with charge $n$ .

Some contributions of Edoardo Ballico to Moduli spaces and their applications

Elizabeth Gasparim

This is a contribution to the Special Volume in Celebration of the 70th Birthday of Edoardo Ballico. First, I describe how some results of Ballico on moduli of vector bundles and c…
