As a contribution requested by the editors of a memorial volume for Peter G O Freund (1936–2018) we recall the lively particle theory group at the Enrico Fermi Institute of the University of Chicago in the late sixties, of which Peter was a memorable member. We also discuss a period some twenty years later when our and Peter’s research overlapped on the topic of p -Adic strings.

六十年代后期在芝加哥的粒子论和p-Adic弦

作为编辑彼得·高·弗洛因德（Peter GO Freund，1936–2018）纪念册的编辑的要求，我们回想起60年代后期芝加哥大学恩里科·费米研究所（Enrico Fermi Institute）活跃的粒子理论小组，其中彼得是令人难忘的成员。我们还讨论了大约二十年后的一段时期，那时我们和Peter的研究重叠在p -Adic字符串这一主题上。
