Maximum Product Over Partitions Into Distinct Parts
... 1 as a part. It follows from the relation p · 1 < p + 1, valid for all positive integers p. Another observation, p + q < pq, valid for all 2 ≤ p < q, implies that a longer partition is preferred over a shorter one. Hence, the product of parts will be maximized by long partitions that do not contain ...

... As well as understanding this example at the informal/intuitive level suggested by the picture above, think about the formula above, and satisfy yourself that it does indeed descibe a bijection between N and Z. If you are convinced that the two questions above (and all others like them) have unique ...

Chapter 8 Number Theory
... Eg. Any subset of size six from S={1,2,3,4,5,6,7,8,9} must contain two elements whose sum is 10. (Sol.) The numbers: 1,2,3,4,5,6,7,8,9 are pigeons. {1,9}, {2,8}, {3,7}, {4,6}, {5} are pigeonholes. When 6 pigeons go to their respective pigeons, they must fill at least one of the two-element subsets w ...
