Comparison of relatively unipotent log de Rham fundamental groups
Bruno Chiarellotto, Valentina Di Proietto, Atsushi Shiho
In this paper, we prove compatibilities of various definitions of relatively unipotent log de Rham fundamental groups for certain proper log smooth integral morphisms of fine log s…

On the homotopy exact sequence for log algebraic fundamental groups
Valentina Di Proietto, Atsushi Shiho
We construct a log algebraic version of the homotopy sequence for a quasi-projective normal crossing log variety over a log point of characteristic zero and prove some exactness pr…

On p-adic invariant cycles theorem
B. Chiarellotto, R. Coleman, V. Di Proietto +1
For a proper semistable curve over a DVR of mixed characteristics we reprove the "invariant cycles theorem" with trivial coefficients (see Chiarellotto, 1999) i.e. that the gro…
