Gauss's Class Number Conjecture
In his monumental treatise Disquisitiones Arithmeticae, Gauss conjectured that the class number 
of an imaginary quadratic field with binary quadratic form discriminant 
tends to infinity with 
. A proof was finally given by Heilbronn (1934), and Siegel (1936) showed that for any 
, there exists a constant 
such that
as 
. However, these results were not effective in actually determining the values for a given 
of a complete list of fundamental discriminants 
such that 
, a problem known as Gauss's class number problem.
Goldfeld (1976) showed that if there exists a "Weil curve" whose associated Dirichlet L-series has a zero of at least third order at 
, then for any 
, there exists an effectively computable constant 
such that
Gross and Zaiger (1983) showed that certain curves must satisfy the condition of Goldfeld, and Goldfeld's proof was simplified by Oesterlé (1985).
