Abstract
We study the functors DB∗(V), where B∗ is one of Fontaine’s period rings and V is a family of Galois representations with coefficients in an affinoid algebra A. We first relate them to (φ,Γ)-modules, showing that DHT(V)=⊕i∈Z(DSen(V)⋅ti)ΓK, DdR(V)=Ddif(V)ΓK, and Dcris(V)=Drig(V)[1∕t]ΓK; this generalizes results of Sen, Fontaine, and Berger. We then deduce that the modules DHT(V) and DdR(V) are coherent sheaves on Sp(A), and Sp(A) is stratified by the ranks of submodules D[a,b]HT(V) and D[a,b]dR(V) of “periods with Hodge–Tate weights in the interval [a,b]@”. Finally, we construct functorial B∗-admissible loci in Sp(A), generalizing a result of Berger and Colmez to the case where A is not necessarily reduced.
