Notation issues

  1. Apr 9, 2005 #1
    I'm trying to read 'Wavelets on the 2-Sphere: A Group Theoretical Approach' by Antoine and Vanderghynst, available at http://citeseer.ist.psu.edu/antoine98wavelets.html. They introduce [tex]\mathbb{R^+_*}[/tex]. Unfortunately, they don't seem to define this anywhere in the paper, and I've never come across such notation before. Anybody got any ideas?

    Could it mean "positive reals excluding zero" ?

    When I was in elementary school, this was what the author of our textbook had it mean (as far as i can remember).

    That makes sense in the context :) thanks
