Natural metric(s) on the unordered configuration space of a metric space
Let $(X, d)$ be a metric space, where $X$ is a non-empty set and $d$ is a metric on $X$. Consider the configuration space $C_n(X)$ of $n$ distinct points in $X$. Is there a natural metric on $C_n(X) / ...

Why do unit quaternions span $S^3$ space, while rigid body configuration represented by them span $S^2 \times S^1$?
I'm reading "Modern Robotics" by Lynch and Park and came to realize that the rigid body configuration space is not $\mathbb{R}^3 \times S^3$, but rather $\mathbb{R}^3 \times S^2 \times S^1$ (...

Configuration space of points on the REAL line
Can anyone kindly provide me with some intro or reference to the configuration space of $n$ points on the real line? The configuration space of $n$ points in $R^d$ is embedded in
$(R^d)^n \times (S^{d-...

The configuration space of 3 unordered points in $\mathbb{R}^2$ with distinct distances
Let $(X, d)$ be a metric space and let $n \in \mathbb{N}$. Define $A_n(X) = \{ (x_i)_{i=1}^n \in X^n \mid \forall i \neq j: x_i \neq x_j \}$ to be the space of $n$ ordered distinct points in $X$. ...

Is this quotient space a manifold?
Consider the configuration space $\text{Conf}_n(\mathbb R^k)$, and consider the subgroup $G=\mathbb R^k\rtimes \mathbb R^{\times}\leq \mathbb R^k\rtimes \text{GL}(k,\mathbb R)=\text{Aff}(\mathbb R^k)$ ...

What is the geometric realization of the configuration simplicial space?
Take a path-connected space $X$ and consider the family of non-empty, ordered configuration spaces $(\text{Conf}_{\bullet+1}(X))$. This collection of spaces forms a semi-simplicial space with face ...

Configuration spaces to moduli spaces
In Segal's paper on Mapping Configuration spaces to moduli spaces, I'm not understanding what the map $\Phi$ is, explicitly.
Also in section 2, he goes on to say $M_{g,2} \simeq BHomeo^{+}(F_{g,2}; \...
