Toward The Largest Gap

x=(1,4,9)x = (1, 4, 9) and y=(5,6,10)y = (5, 6, 10), so the coordinate gaps are 4,2,14, 2, 1. The Minkowski distance is

dp(x,y)=(∑i∣xi−yi∣p)1/pd_p(x,y) = \left(\sum_i |x_i - y_i|^p\right)^{1/p}

pp dp(x,y)d_p(x,y)
1 7.000
2 4.583
4 4.065
10 4.001

What is lim⁡p→∞dp(x,y)\lim_{p \to \infty} d_p(x,y), and how does the sequence approach it?

A

0, since the 1/p1/p exponent drives everything toward 1

B

4, approached from above as the values decrease

C

7, the Manhattan distance, since that is the largest value in the table

D

4, approached from below as the values increase with pp
