 Title: Class Number Two for Real Quadratic Fields of Richaud-Degert Type Authors: Mollin, R. A. Keywords: Quadratic FieldsPrime-Producing PolynomialsClass NumbersContinued FractionsCycles of IdealsRichaud-Degert Types Issue Date: 2009 Publisher: Institute of Mathematics and Informatics Bulgarian Academy of Sciences Citation: Serdica Mathematical Journal, Vol. 35, No 3, (2009), 287p-300p Abstract: This paper contains proofs of conjectures made in [16] on class number 2 and what this author has dubbed the Euler-Rabinowitsch polynomial for real quadratic fields. As well, we complete the list of Richaud-Degert types given in [16] and show how the behaviour of the Euler-Rabinowitsch polynomials and certain continued fraction expansions come into play in the complete determination of the class number 2 problem for such types. For some values the determination is unconditional, and for others, the wide Richaud-Degert types, the determination is conditional on the generalized Riemann hypothesis (GRH).
