   • 2016, O. Mata-Gutiérrez, Frank Neumann, “Geometry of Moduli Stacks of ${\displaystyle (k,l)}$-stable vector bundles over an algebraic curve”, in arXiv^[1]:

     We study the geometry of the moduli stack of vector bundles of fixed rank and degree over an algebraic curve by introducing a filtration made of open substacks build from ${\displaystyle (k,l)}$-stable vector bundles. ${\displaystyle (k,l)}$-stability was introduced by Narasimhan and Ramanan to study the geometry of the coarse moduli space of stable bundles.
