Differential Chow Form for Projective Differential Variety
, 2011 In this paper, a generic intersection theorem in projective differential algebraic geometry is presented. Precisely, the intersection of an irreducible projective differential variety of dimension d>0 and order h with a generic projective differential ...

Inner Ideals and Intrinsic Subspaces of Linear Pair Geometries [PDF]
arXiv, 2006 We introduce the notion of intrinsic subspaces of linear and affine pair geometries, which generalizes the one of projective subspaces of projective spaces. We prove that, when the affine pair geometry is the projective geometry of a Lie algebra introduced in [Bertram-Neeb, J. Alg.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Objective To develop and validate a HyperArc‐based RapidPlan (HARP) model for three‐fraction brain stereotactic radiotherapy (SRT) plans to then use to replan previously treated five‐fraction SRT plans. Demonstrating the possibility of reducing the number of fractions while achieving acceptable organs‐at‐risk (OAR) doses with improved target ...

Geometry of the quantum projective plane
, 2009 We review some of the geometry of the quantum projective plane with emphasis on the construction of a differential calculus and of the Dirac operator (of a spin^c-structure). We also report on anti-self-dual connections on line bundles, the spectrum of associated (gauged) Laplacian operators, and on classical and quantum characteristic classes.
