Stabilized symplectic embeddings of higher-dimensional ellipsoids
Shah Faisal
We provide a lower bound for the embedding capacity of higher-dimensional symplectic ellipsoids, formulated in terms of the Lagrangian capacity of ellipsoids. Our approach relies o…

Higher-rank instantons sheaves on Fano threefolds
Gaia Comaschi, Daniele Faenzi
We define instanton sheaves of higher rank on smooth Fano threefolds X of Picard rank one and show that their topological classification depends on two integers, namely the rank n…
