Two circles and only a straightedge

We answer a question of David Hilbert: given two circles it is not possible in general to construct their centers using only a straightedge. On the other hand, we give infinitely m…

Motivic classes of moduli of Higgs bundles and moduli of bundles with connections

Roman Fedorov, Alexander Soibelman, Yan Soibelman

Let X be a smooth projective curve over a field of characteristic zero. We calculate the motivic class of the moduli stack of semistable Higgs bundles on X. We also calculate the m…
