Let $F$ be a totally real number field and let $f$ be a classical cuspidal $p$-regular Hilbert modular eigenform over $F$ of parallel weight $1$. Let $x$ be the point on the $p$-adic Hilbert eigenvariety $\mathcal E$ corresponding to an ordinary $p$-stabilization of $f$. We show that if the $p$-adic Schanuel Conjecture is true, then $\mathcal E$ is smooth at $x$ if $f$ has CM. If we additionally assume that $F/\mathbb Q$ is Galois, we show that the weight map is \'etale at $x$ if $f$ has either… Expand

On generalized Iwasawa main conjectures and $p$-adic Stark conjectures for Artin motives
We formulate a cyclotomic main conjecture and an extra zeros conjecture for general p-stabilized Artin representations, which are shown to imply the p-part of the Tamagawa number conjecture for ArtinExpand

On the failure of Gorensteinness at weight 1 Eisenstein points of the eigencurve
We prove that the cuspidal $p$-adic eigencurve $C_{cusp}$ is etale over the weight space at any classical weight $1$ Eisenstein point $f$. Further we show that $C_{cusp}$ meets transversely at $f$Expand

In this paper, we prove that, to any Hilbert cuspidal eigenform, one may attach a compatible system of Galois representations. This result extends the analogous results of Deligne and Deligne–SerreExpand
