<div> <div> <div> <p>Let K be a discrete valuation field with perfect residue field, we study the functor from weakly admissible filtered (φ,N,G_K)-modules over K to the isogeny category of Breuil- Kisin-Fargues G_K-modules. This functor is the composition of a functor defined by Fargues-Fontaine from weakly admissible filtered (φ,N,G_K)-modules to G_K-equivariant modifications of vector bundles over the Fargues-Fontaine curve X_FF , with the functor of Fargues-Scholze that between the category of admissible modifications of vector bundles over X_FF and the isogeny category of Breuil-Kisin-Fargues modules. We characterize the essential image of this functor and give two applications of our result. First, we give a new way of viewing the p-adic monodromy theorem of p-adic Galois representations. Also we show our theory provides a universal theory that enable us to compare many integral p-adic Hodge theories at the A_inf level. </p> </div> </div> </div>
