Tame Fontaine–Mazur conjecture

About 9 years old · traced to

Let pp be a prime, let KK be a number field, and let SS be a finite set of places of KK not dividing pp. Let KSK_S be the maximal pro-pp extension of KK unramified outside SS, and write GS:=Gal⁡(KS/K)G_S:=\operatorname{Gal}(K_S/K). Tame Fontaine–Mazur conjecture. For every positive integer nn, every continuous representation ρ:GS→GLn(Qp)\rho:G_S\to GL_n(\mathbb{Q}_p) has finite image. This is the finitely and tamely ramified analogue of the weak Fontaine–Mazur conjecture. The source notes that the one-dimensional case follows from class field theory, while the higher-dimensional case remains open in general.
