But the k here and the k in VDW are not entirely different. Any large AP would have to have at least k elements (since a large AP beginning at m needs to have m terms, and m >= k.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-9110279824103846922009-01-13T07:58:00.000-06:002009-01-13T07:58:00.000-06:00What is k in the statement of VDW's theorem?

For example, under the interpretations of that definition that I'm imagining, I don't see why (4,5,6,7) would be large.Anonymousnoreply@blogger.com
