Abstract

Asymptotic syzygies of a normal crossing variety follow the same vanishing behavior as one of its smooth components, unless there is a cohomological obstruction arising from how the smooth components intersect each other. In that case, we compute the asymptotic syzygies in terms of the cohomology of the simplicial complex associated to the normal crossing variety.

We combine our results with knowledge of degenerations of certain smooth projective varieties into normal crossing varieties to obtain some results on asymptotic syzygies of those smooth projective varieties.
