Weak and strong Lefschetz properties for Hartshorne-Rao modules of curves in $\mathbb P^3$
The authors prove maximal-rank multiplication by general linear forms on Hartshorne-Rao modules of general unions of skew lines, establish the weak Lefschetz property for curves on quadrics and most unions of skew lines, construct counterexamples for certain larger configurations and a degree-15 irs
