On the number of real quadratic fields with class number divisible by 3,
... Now the only thing we have to check is that there are a negligible number of duplications among these fields. Let S be the set of D(f )’s counted above which give rise to same fields more than once. For such a D(f ) in S, 4a31 + 27b21 = c2 (4a32 + 27b22), 4(a31 − c2 a32 ) = 27(b2 c + b1 )(b2 c − b1 ...

... Definition 1: If a and b are integers with a ≠ 0, we say that a divides b if there is an integer c such that b = ac. When a divides b we say that a is a factor of b and that b is multiple of a. The notation a | b denotes that a divides b. We write a | b when a does not divide b. THEOREM 1: Let a, b ...

... But as k → ∞ each of these fractions tends to the limit β, and so α = β as required. To prove uniqueness, suppose that we have two infinite simple continued fractions representing the same number, [a0 , a1 , a2 , . . .] = [b0 , b1 , b2 , . . .] . For any k, we can write these in the form [a0 , a1 , ...
