Deletion of Arif Zaman

Comment: Google Scholar shows citation counts of 546, 504, 161, 116, 105, 67, 44, 41, ... I think that's enough for #C1, especially for a mathematician. I'm more interested in the high end of the citation count (the ones with over 100 citations) and in this case the h-index doesn't really show that. I think this record is a lot stronger than someone with the same h-index=12 but with peaks in the low double digits. I deleted some unsourced content from the article and added another source, so I don't think we have a big problem with verifiability or sourcing for content
