| contents | Let \(C\) be a smooth projective curve over an algebraically closed field of characteristic zero. For the moduli space \(N(r,L)\) of stable vector bundles on \(C\) of rank \(r\) with fixed determinant \(L\), we study the group of exact autoequivalences of its bounded derived category. Combining the Bondal--Orlov reconstruction theorem with the descriptions of \(\operatorname{Aut}(N(r,L))\) due to Kouvidakis--Pantev and Newstead, we obtain an explicit description of \(\operatorname{Aut}\mathrm{D^b}(N(r,L))\). We also construct extension correspondences between moduli spaces of vector bundles of different ranks and use them to define natural Fourier--Mukai type exact functors between their bounded derived categories. |
