Abstract
We review our recent paper, where we proved Parton distributions functions (PDFs) to be positive at NLO in the $\overline{MS}$ factorization scheme. We present some additional material that was useful in completing the steps for the actual proof, but we won't attempt to report on the full proof, but referring the reader to the paper itself.

Report
Interesting and important results on the positivity of PDFs in the MSbar scheme.
Only two minor grammatical comments: 1. In the first sentence of the conclusion, "posivitiy" should read "positivity", and 2. In the same sentence, the word "space" is repeated twice "momentum fraction space space".
