Taylor Morphisms
Gabriel Ng
We study generalised Taylor morphisms, functors which construct differential ring homomorphisms from ring homomorphisms in a uniform way, analogous to the Taylor expansion for smoo…

Tressl's Structure Theorem for Separable Algebras
Gabriel Ng
This short paper presents a generalisation of Tressl's structure theorem for differentially finitely generated algebras over differential rings of characteristic 0 to the case of s…

Differentially Henselian Fields
Gabriel Ng
We study the class of differentially henselian fields, which are henselian valued fields equipped with generic derivations in the sense of Cubides Kovacics and Point, and are speci…
