I begin to study some p-adic analysis. I find it is hard to understand the infraconnected set and affinoid. It is strange that I cannot find them at wiki and only a few book(by the same auther) discuss them, but also no simple example. Does them has other names?
1)Please give me some standard simple examples to show thet what is the infraconnected set looks like.
2)Is the infraconnected set relate with the connected set in the topology?
3)I also find a related concept called empty annulus, does it has some special meaning in the p-adic analysis?
4) The affinoid set means bounded closed infraconnected set with finitely many holes, what is the holes here?
A similar question is at here.
