Abstract

We define higher pro-Albanese functors for every effective log motive over a field kk of characteristic zero, and we compute them for every smooth log smooth scheme X=(X,X)X=(\underline{X}, \partial X). The result involves an inverse system of the coherent cohomology of the underlying scheme as well as a pro-group scheme Alblog(X)\mathrm{Alb}^{\log}(X) that extends Serre's semi-abelian Albanese variety of XX\underline{X}-|\partial X|. This generalizes the higher Albanese sheaves of Ayoub, Barbieri-Viale and Kahn.
