The authors are grateful to Ulrich Derenthal and Brendan Hassett for several useful conversations relating to universal torsors for singular del Pezzo surfaces. Special thanks are due to Roger Heath–Brown whose ideas led us to the proof of Lemma 6. The paper was finalised while the first author was at the École Normale Supérieure, and the second author was at Oxford University supported by EPSRC grant number GR/R93155/01. The hospitality and financial support of these institutions is gratefully acknowledged. Finally, the authors would like to thank the anonymous referee for his careful reading of the manuscript and numerous useful suggestions.","lang":"eng"}],"title":"On Manin's conjecture for singular del Pezzo surfaces of degree four, II","doi":"10.1017/S0305004107000205","year":"2007","status":"public","extern":1,"volume":143,"_id":"222","publication":"Mathematical Proceedings of the Cambridge Philosophical Society","type":"journal_article","day":"01","citation":{"ama":"De La Bretèche R, Browning TD.
