plural of Alcubierre metric

(mathematical analysis) The metric 𝜌(f,g)= sup _(x∈X) where f and g are functions on X.

(mathematical analysis) In the abstract metric space of all compact subsets of ℝⁿ, given a pair of compact sets A and B, the Hausdorff metric is h(A,B)= mbox max𝜌(A,B),𝜌(B,A) where 𝜌(A,B)= sup _(a∈A) inf _(b∈B),d(a,b), where d is the Euclidean metric in ℝⁿ.

(mathematical analysis) In the space ℝⁿ, the metric d(⃑x,⃑y)=√ where ⃑x=(x_1,...,x_n) and ⃑y=(y_1,...,y_n).

(mathematical analysis) a metric d such that for any pair of points x and y, d(x,y)=0 if x=y and d(x,y)=1 if x ne y.
