The geometry of von-Neumann's pre-measurement and weak values
  We have carried out a review of a paper from Tamate et al, conducting a deeper study of the geometric concepts they introduced in their paper, clarifying some of their results and calculations and advancing a step futher in their geometrization program for an understanding of the structure of von-Neumann's pre-measurement and weak values.
