Reason: First published version. A sequence in a metric space has at most one limit. The corpus previously had this only for real sequences in the separate c54 framework, leaving no way to identify two limits of the same sequence in a general metric space.

Statement

Let $(X,d)$ be a metric space, let $(x_m)_{m\in\mathbb{N}}$ be a sequence in $X$ , and let $x,y\in X$ .

If $(x_m)_{m\in\mathbb{N}}$ converges to $x$ in $(X,d)$ and also converges to $y$ in $(X,d)$ , then $x=y$ .
