Abstract

We prove in this article that given a linearly concave domain DD in the projective space CPn\Bbb{CP}^{n}, a 1-dimensional comlex analytic set VV in DD, and a meromorphic 1-form ϕ\phi on VV, VV is a subset of an algebraic variety of CPn\Bbb{CP}^{n} and ϕ\phi is the restriction to VV of an algebraic 1-form on CPn\Bbb{CP}^{n} if and only if the Abel transform A(ϕ[V])A(\phi \wedge [V]) of the analytic current ϕ[V]\phi \wedge [V] is an algebraic 1-form on (CPn)(\Bbb{CP}^{n})*, where an algebraic 1-form on CPn\Bbb{CP}^{n} is a meromorphic 1-form defined on a ramified analytic covering of CPn\Bbb{CP}^{n}. This result has its origin in the general inverse Abel theorems of Lie, Darboux, Saint-Donat, Griffiths and Henkin.
