Gromov–Hausdorff closure of non-positively curved graphs
Setup:
Let $\Gamma$ be the set of non-positively curved weighted connected graphs, with finitely many points, which are isometrically embedded in $\mathbb{R}^n$; for some $n\in \mathbb{N}$;$n\geq 2$. ...

Does the lemma remain valid in b-metric space?
Let $(X,d)$ be a complete metric space.
$$CB(X)=\{A : A \text{ is a nonempty closed and bounded subset of }X \},$$
$$D(A,B)=\inf \{d(a,b) : a\in A , b\in B\},$$
$$\sigma (A,B)=\sup \{d(a,b) : a\in A , ...
