The author’s abstract: “We prove that given a linearly concave domain \(D\) in the projective space \(CP^n\), a 1-dimensional complex analytic set \(V\) in \(D\), and a meromorphic 1-form \(\varphi\) on \(V\), \(V\) is a part of an algebraic variety of \(CP^n\) and \(\varphi\) the restriction of \(V\) of an algebraic 1-form on \(CP^n\) if and only if the Abel transform \(A(\varphi\wedge [V])\) of the analytic current \(\varphi\wedge[V]\) is an algebraic 1-form on the dual \((CP^n)^*\), where an algebraic 1-form on \(CP^n\) is a meromorphic 1-form defined on a ramified analytic covering of \(CP^n\). This result has its origin in the general inverse Abel theorems of Lie, Darboux, Saint-Donat, Griffiths and Henkin”.
