Jan 29, 2010 at 9:51	comment	added	Chandan Singh Dalawat		By "vectorial line" I mean a line passing though the origin in the $\mathbb{F}_p$-space $K^\times/K^{\times p}$, as opposed to an "affine line" in this vector space of dimension $2+[K:\mathbb{Q}_p]$ over $\mathbb{F}_p$. It is perhaps a pedantic way of saying "order-$p$ subgroup". As for the dimension, see Part V of arXiv:0711.3878.
Jan 29, 2010 at 6:12	comment	added	Rado		thanks for the interesting toy example. When you say vectorial lines in $K^\times / K^{\times p}$ is there a way of visualizing this or the algebra is all we have left at this point. I am guessing there is non, but then again p-adic numbers can be visualized quite nicely as branched trees.
