Deformations, local freeness, and base change for higher Du Bois singularities
Haoming Ning
We prove that strict higher Du Bois singularities are invariant under small deformations. Using this, we prove a base change theorem for the relative Du Bois complex with strict hi…

Higher Du Bois and Higher Rational Pairs
Haoming Ning, Brian Nugent
We extend the notions of higher Du Bois and higher rational singularities to pairs in the sense of the minimal model program. We extend numerous results to these higher pairs, incl…

Symplectic embeddings of four-dimensional polydisks into half integer ellipsoids
Leo Digiosia, Jo Nelson, Haoming Ning +2
We obtain new sharp obstructions to symplectic embeddings of four-dimensional polydisks into four-dimensional ellipsoids when and is a half-integ…
