Tamely ramification
Web2. L/K is tamely ramified if and only if G 1 = 1. In particular, if we write the ramification index as e = qnm with (m,q) = 1 and q = chark, then #G 1 = qn and this divides #l. … Web20 Nov 2024 · The difference between tame and wild ramification plays a crucial role in positive characteristic algebraic geometry.

In geometry, ramification is 'branching out', in the way that the square root function, for complex numbers, can be seen to have two branches differing in sign. The term is also used from the opposite perspective (branches coming together) as when a covering map degenerates at a point of a space, with some … See more In complex analysis, the basic model can be taken as the z → z mapping in the complex plane, near z = 0. This is the standard local picture in Riemann surface theory, of ramification of order n. It occurs for example in the See more In a covering map the Euler–Poincaré characteristic should multiply by the number of sheets; ramification can therefore be … See more In valuation theory, the ramification theory of valuations studies the set of extensions of a valuation of a field K to an extension field of K.

WebRemark 13.1 This notion of \tame extension" does not coincide with the notion of \tamely rami ed extension" as de ned in the book of O. Endler [END8], page 180. The latter de nition requires (TE1) and (TE2), but not necessarily (TE3). Our tame extensions are the defectless tamely rami ed extensions in the sense of Endler’s book.
