摘要翻译:
讨论了光滑有理连通曲面的强有理连通性。我们证明了在许多情况下,包括对数del Pezzo曲面的光滑轨迹,有理连通性确实包含了强有理连通性。这证实了由Hassett和Tschinkel在\cite{ht08}中提出的一个猜想。

英文摘要:
We discuss the strong rational connectedness of smooth rationally connected surfaces. We prove in lots of cases, including the smooth locus of a log del Pezzo surface, the rational connectedness indeed implies the strong rational conectedness. This confirms a conjecture due to Hassett and Tschinkel in \cite{ht08}.
