Abstract

Given a vector bundle EE on a smooth projective curve or surface XX carrying the structure of a VV-twisted Hitchin pair for some vector bundle VV, we observe that the associated tautological bundle E[n]E^{[n]} on the punctual Hilbert scheme of points X[n]X^{[n]} has an induced structure of a ((V)[n])((V^\vee)^{[n]})^\vee-twisted Hitchin pair, where (V)[n](V^\vee)^{[n]} is a vector bundle on X[n]X^{[n]} constructed using the dual VV^\vee of VV. In particular, a Higgs bundle on XX induces a logarithmic Higgs bundle on the Hilbert scheme X[n]X^{[n]}. We then show that the known results on stability of tautological bundles and reconstruction from tautological bundles generalize to tautological Hitchin pairs.
