• Functional analysis and exterior calculus on mixed-dimensional geometries 

      Boon, Wietse; Nordbotten, Jan Martin; Vatne, Jon Eivind (Journal article; Peer reviewed, 2020-07-12)
      We are interested in differential forms on mixed-dimensional geometries, in the sense of a domain containing sets of d-dimensional manifolds, structured hierarchically so that each d-dimensional manifold is contained in ...
    • Ulrich bundles on a general blow-up of the plane 

      Ciliberto, Ciro; Flamini, Flaminio; Knutsen, Andreas Leopold (Journal article; Peer reviewed, 2023)
      We prove that on X n , the plane blown-up at n very general points, there are Ulrich line bundles with respect to a line bundle corresponding to curves of degree m passing simply through the n blown-up points, with m ≤ 2√n ...
