Abstract: Let \(p\) be a prime number, \(K\) a finite unramified extension of \(\mathbf{Q}_p\), and \(\pi\) a smooth representation of \(\mathrm{GL}_2(K)\) on some Hecke eigenspace in the \(H^1\) mod \(p\) of a Shimura curve. One can associate to \(\pi\) a multivariable \( (\phi, O_K^*)\)-module \(D_A(\pi) \). I will state a conjecture which describes \( D_A(\pi) \) in terms of the underlying 2-dimensional mod \(p\) representation of \(\mathrm{Gal}(\bar{K}/K)\). When the latter is semi-simple (sufficiently generic), I will sketch a proof of this conjecture. This is joint work with F. Herzig, Y. Hu, S. Morra and B. Schraen.
