Orbifold Cartan conjecture for ramified holomorphic curves

About 14 years old · traced to

Let H1,…,HqH_1,\dots,H_q be hypersurfaces of degrees did_i in Pn{\mathbb P}^n in general position. Let f:C→Pnf:{\mathbb C}\to{\mathbb P}^n be a holomorphic curve that ramifies over HiH_i with multiplicity divisible by mim_i.

Orbifold Cartan conjecture. If

∑i(1−1mi)di>n+1,\sum_i\left(1-\frac{1}{m_i}\right)d_i>n+1,

then ff is algebraically degenerate, meaning that its image is contained in a proper algebraic hypersurface.

This is the hypersurface formulation of the orbifold Green–Griffiths–Lang conjecture and is presented as an unsolved problem in the paper.
