Abstract: We construct a certain variant of Liu's $(\varphi, \hat{G})$-modules to classify integral semi-stable Galois representations. Our theory uses Breuil-Kisin modules and Breuil-Kisin-Fargues modules with Galois actions, and can be regarded as the algebraic avatar of the integral p-adic cohomology theories of Bhatt-Morrow-Scholze and Bhatt-Scholze. Along the way, we classify Galois representations that are finite height in terms of Breuil-Kisin modules.
