      Kukalaj, Endrit (Masteroppgave/UIS-TN-IMF/2020;, Master thesis, 2020-07-09)
      In the introductory chapter, we will explain briefly what all this work is about. First is worthy to mention that the most included area is algebraic geometry, which of course is a combination of algebra and linear algebra. ...
    • Wick-rotations of pseudo-Riemannian Lie groups 

      Helleland, Christer (Peer reviewed; Journal article, 2020)
      We study Wick-rotations of left-invariant metrics on Lie groups, using results from real GIT (Helleland and Hervik, 2018; Helleland and Hervik, 2019). An invariant for Wick-rotation of Lie groups is given, and we describe ...
