Difference ,between, rigid centralizers and semi-rigid centralizers. 2016-08-24 14:17:49. Rigid centralizers are built out of solid steel bar or cast iron, with a fixed blade height and are sized to fit a specific casing or hole size. This type is rugged and works well even in deviated wellbores, regardless of the side force.

Why it’s called the “center” of the group : math

Big difference ,between, pointwise-stable and set-wise-stable. So in some sense it is fixed in the ,"center", of the ,group, as OP says, you just have to be more specific about what you mean by "fixed". I have no idea if this is the historical origin of the term though.

Why it’s called the “center” of the group : math

That’s true. I think because “less” abelian groups are typically more interesting, the ,center, got its name because it’s smaller in this case and since the ,center, of a shape is a single point the ,center of a group, should be relatively small as well. Probably a huge reach but still interesting to think about
