Abstract
Let k be an algebraically closed field of characteristic \(p > 3\) and S be a smooth projective surface over k with k-rational point x. For \(n \ge 2\), let \(S^{[n]}\) denote the Hilbert scheme of n points on S. In this note, we compute the fundamental group scheme \(\pi ^{\text {alg}}(S^{[n]}, {\tilde{nx}})\) defined by the Tannakian category of stratified bundles on \(S^{[n]}\).
