Given two sets, S1 and S2, S1 is "k-thick" in S2 if for every sequence of intervals (ai,bi) such that bi-ai goes to infinity, the sequence of ratios of the sizes of the intersections between S1 with (ai,bi), and S2 with (ai,bi), has limit k. By this definition the set of primes is 0-thick in the integers, as is the set of powers of two. This is less helpful than you probably want, but generally this sort of definition can be made local. -- \\// ze'uku ko jmive gi'e snada ------------------------------------------------------------------------ Free Worldwide Calling with Firetalk!
