The term "cluster point" in French mathematical literature is translated as "valeur d'adhérence." This concept is related to adherent points, which are defined such that every epsilon-ball around the point contains at least one point from the set. The discussion highlights that while every cluster point is adherent, not every adherent point qualifies as a cluster point. Additionally, "point d'accumulation" is mentioned as a related term, but it faces similar definitional challenges. The conversation emphasizes the nuances in definitions within the context of metric spaces and sequences.
