A residue current associated with a twisting cochain: duality and comparison formula

Jimmy Johansson

Let $F^{∙}$ be a complex of coherent $O_{X}$ -modules over a complex manifold $X$ . We give a construction of a residue current associated with this complex tha…

An explicit isomorphism of different representations of the Ext functor using residue currents

Jimmy Johansson, Richard Lärkäng

Let $F$ be a coherent $O_{X}$ -module over a complex manifold $X$ , and let $G$ be a vector bundle on $X$ . We describe an explicit isomorphism between two different…

Polynomial interpolation and residue currents

Jimmy Johansson

We show that a global holomorphic section of $O (d)$ restricted to a closed complex subspace $X \subset P^{n}$ has an interpolant if and only if it satisfies a set…
