Research Article

  • Commutative Involutions

  • R. L. Goodstein
  • Published online by Cambridge University Press:
    03 November 2016, pp. 224-226

  • We prove some theorems on commutative involutions in a “real” projective geometry in which cobasal homographie ranges may have 0, 1 or 2 self-corresponding points (and therefore a conic and a general line in its plane have 0, 1 or 2 points of intersection).
