Differential invariants on symplectic spinors in contact projective geometry [PDF]
Journal of Mathematical Physics, 2017 We present a complete classification and the construction of Mp(2n+2,R)-equivariant differential operators acting on the principal series representations, associated with the contact projective geometry on RP2n+1 and induced from the irreducible Mp(2n,R)-submodules of the Segal–Shale–Weil representation twisted by a one-parameter family of characters ...

Surface theory in discrete projective differential geometry. I. A canonical frame and an integrable discrete Demoulin system [PDF]
Proceedings of the Royal Society A, 2018 We present the first steps of a procedure which discretizes surface theory in classical projective differential geometry in such a manner that underlying integrable structure is preserved.

General Projective Differential Geometry [PDF]
Proceedings of the National Academy of Sciences, 1937 tion of the feathers in the different tracts clearly shows the importance of position in feather tract characterization at the stage of operation. This is further emphasized by the fact that the skin ectoderm implant came in all cases from the head where

Walls and asymptotics for Bridgeland stability conditions on 3-folds [PDF]
Épijournal de Géométrie Algébrique, 2022 We consider Bridgeland stability conditions for three-folds conjectured by Bayer-Macr\`i-Toda in the case of Picard rank one. We study the differential geometry of numerical walls, characterizing when they are bounded, discussing possible intersections ...

Terracini Loci: Dimension and Description of Its Components
Mathematics, 2023 We study the Terracini loci of an irreducible variety X embedded in a projective space: non-emptiness, dimensions and the geometry of their maximal dimension’s irreducible components.
