AI 中文摘要
本文以两种概念的支持者之间的辩论形式，对比了真凝聚体（proper condensate）与玻色-爱因斯坦凝聚的Onsager-Penrose判据的概念。序幕简要介绍了这两种判据，尾声包含了与该语境物理相关的基础预解式代数（resolvent algebra）性质的评述。
英文摘要
This article contrasts the concepts of a proper condensate and the Onsager-Penrose criterion for Bose-Einstein condensation in the form of a debate between two proponents of the respective concepts. The prologue briefly introduces the two criteria. The epilogue contains remarks on properties of the underlying resolvent algebra that are physically relevant in this context.
