Information Geometry of Positive Definite Matrices

    Graphical Abstract
    • Abstract
  • A new Riemannian metric for positive definite matrices is defined and its geometric structures are investigated by means of dual connections introduced to statistical analysis by S. Amari. A few interesting results are obtained and some of those obtained by other authors are extended in our research.
