Talk:Dilation (metric space)

From Wikipedia, the free encyclopedia
Jump to: navigation, search

The article is contradictory as it stands. According to the definition on the page, a translation is a dilation. A translation does not have a fixed point, however.


The article is not comprehensible to the non-expert. Compare with [1]. —DIV ( (talk) 00:05, 29 January 2009 (UTC))

Possible Duplication[edit]

Is this the same as Scaling (geometry)? Should the articles be merged? Rojomoke (talk) 15:59, 24 April 2009 (UTC)

No, for two reasons:
  1. The transformations described in the scaling algorithm don't allow for rotations; the ones here do, and
  2. This is about general metric spaces, not just Euclidean spaces.
