We present various results about Euclidean preferences in the plane under 1 , 2 and ∞ norms. When there are four candidates, we show that the maximum size (in terms of the number of pairwise distinct preferences) of Euclidean preference profiles in R 2 under norm 1 or ∞ is 19. ...
Euclidean范数指得就是通常意义上的距离范数。比如||X||=ρ(X,0)=Sqrt(X1^2+X2^2+...+Xn^2)
A vector median filter based on a fast approximation of the Euclidean norm is presented. The proposed algorithm couples computational and filtering effectiveness, and it is well suited for hardware implementation. Theoretical and experimental results regarding both approximation error and speed improvement ...

We give examples of Generalized Euclidean but not norm-Euclidean number fields of degree greater than 2. In the same way we give examples of 2-stage Euclidean but not norm-Euclidean number fields of degree greater than 2. In both cases, no such examples were known. DOI: 10.1090/S0025-5718...
