The pp-adic section conjecture for curves

Let k/Qpk/\mathbb Q_p be a finite extension, and let X/kX/k be a smooth, projective and geometrically connected curve of genus at least 22. A rational point aX(k)a\in X(k) determines a section sa:Galkπ1(X)s_a:\operatorname{Gal}_k\to\pi_1(X), and sections are considered up to conjugacy by π1(X)\pi_1(\overline{X}). The pp-adic section conjecture. The map

a[sa]a\longmapsto [s_a]

is a bijection from X(k)X(k) onto the set of π1(X)\pi_1(\overline{X})-conjugacy classes of sections of π1(X/k)\pi_1(X/k). This is the local analogue of Grothendieck's section conjecture. The paper describes evidence for it, but the asserted bijectivity remains open.
