The Dissection of Rectangles Into Squares,e . into a finite number . of non-overlapping squares is called a . of . of .; and the . squares are the . of the dissection. The term “elements” is also used for the lengths of the sides of the elements. If there is more than one element and the elements are all unequal, the squaring is called ., and . is a ..

A Partition Calculus in Set Theory, as follows. .. In 1930 F. P. Ramsey discovered a remarkable extension of this principle which, in its simplest form, can be stated as follows. Let . be the set of all positive integers and suppose that all unordered pairs of distinct elements of . are distributed over two classes.
