| Jul 27, 2011 at 7:40 | comment | added | Maurizio Monge | @Alex: however the ramification degree is NOT multiplicative while taking the compositum. You can observe what is going on locally over $\mathbb{Q}_p$, any two distinct totally ramified Galois extensions of degree $p$ generate the maximal abelian elementary $p$-extension, which contains an unramified part. | |
