Ramsey Theory, Integer Partitions and a New Proof of the Erd˝os
... S ⊆ [n]d is a down-set if s ∈ S implies x ∈ S for all x s. We will frequently use the following simple observation stating that any down-set can be viewed as a d − 1-dimensional partition. This is best explained by Figures 1a and 1b, but we include the formal proof for completeness. Observation 2. ...

... | {z } | {z } However, with k = 2 we ran into difficulties. The approach appeared to fail for all periods N ≤ 60. For example, when we set our period at 60 (a smooth number which is likely to yield results), we cover either 2 · b15 + 1 or 2 · b45 + 1 but not both. When we set the period at 48, this ...

... To add or subtract complex numbers, add or subtract their real parts and then add or subtract their imaginary parts. Adding complex numbers is easy. To multiply complex numbers, use the rule for multiplying binomials. After you are done, remember that i 2 1 and make the substitution. In fact, if ...
