What Does Mean Ortocrone Group

  1. Jul 9, 2010 #1
    When I searched "ortocrone" with google, I found only 93 results. Most of all results were Spanish. Now I wonder history of ortocrone group.

    I've never heard of an ortocrone group. The spelling makes me think of the orthochronous Lorentz group, the first word of which may be ortocrone in Spanish. Where did you see this?

    That looks like the orthochronous subgroup of the Lorentz group, so you should probably google "orthochronous" instead of "ortocrone".
