Abstract

Let $k$ be a number field. We describe the category of Laumon $1$-isomotives over $k$ as the universal category in the sense of Nori associated with a quiver representation built out of smooth proper $k$-curves with two disjoint effective divisors and a notion of $H^1_\mathrm{dR}$ for such "curves with modulus". This result extends and relies on the theorem of J. Ayoub and L. Barbieri-Viale that describes Deligne's category of $1$-isomotives in terms of Nori's Abelian category of motives.
Keywords: motive, curve with modulus, quiver representation motive, curve with modulus, quiver representation
