Agglomeration-based geometric multigrid schemes for the Virtual Element Method Autor Antonietti, Paola Francesca, Berrone, Stefano, Busetto, Martina, Verani, Marco

“… The sequence of agglomerated tessellations are nested, but the corresponding multilevel virtual discrete spaces are generally non-nested thus resulting into non-nested multigrid algorithms…”
