Ramsey functions for quasi-progressions with large diameter
Ramsey functions for quasi-progressions with large diameter
A k-term quasi-progression of diameter d is a sequenceof positive integers for which there exists a positive integer l such that l ≤ x jx j-1 ≤ l + d, for all j = 2, . . ., k.Let Q (d, k) be the least positive integer such that every …
