    • Preserved Structure Constants for Red Refinements of Product Elements 

      Korotov, Sergey; Vatne, Jon Eivind (Chapter; Peer reviewed, 2021)
      In this paper we discuss some strategy for red refinements of product elements and show that there are certain structure characteristics (d-sines of angles formed by certain edges in the initial partition) which remain ...

    • Tight bounds for the dihedral angle sums of a pyramid 

      Korotov, Sergey; Lund, Lars Fredrik Kirkebø; Vatne, Jon Eivind (Peer reviewed; Journal article, 2022)
      We prove that eight dihedral angles in a pyramid with an arbitrary quadrilateral base always sum up to a number in the interval (3π, 5π). Moreover, for any number in (3π, 5π) there exists a pyramid whose dihedral angle sum ...
