    • Moreau-yosida regularization of degenerate state-dependent sweeping processes 
      Narváez, Diana; Vilches, Emilio (Springer, 2022)
      In this paper, we introduce and study degenerate state-dependent sweeping processes with nonregular moving sets (subsmooth and positively alpha-far). Based on the Moreau-Yosida regularization, we prove the existence of ...
