Generalized Terao conjecture for d-arrangements
Generalized Terao conjecture for d-arrangements
Let be two -arrangements for a fixed . Let and be their associated Levi graphs. Generalized Terao conjecture. If and are isomorphic and is free, then is also free.
This asks whether freeness of a -arrangement is determined by the isomorphism class of its Levi graph, extending Terao's conjecture from line arrangements to arrangements of curves. The source presents it as a question, and no resolution is supplied here.
