Incidence problems in discrete geometry
, 2017 Over the past decade, discrete geometry research has flourished with clever uses of algebraic methods. The polynomial method has had a deep impact on a wide collection of results in combinatorics, such as tight asymptotic lower bounds on finite field Kakeya and Nikodym sets, near optimal lower bound for Erdos' distinct distances problem, and improved ...

Geometry of Deformations via Incidence Varieties [PDF]
We provide a unified geometric realization of the classical deformation complexes. We construct GL-equivariant bilinear incidence varieties whose diagonal slices recover the varieties of associative, commutative, Leibniz, and Lie algebra structures on a finite-dimensional vector space. We prove that the fiber of the incidence map at a given algebra law

Linear Geometry: classical incidence properties
Linear Geometry describes geometric properties that depend on the notion of a line. The fundamental structure studied in Linear Geometry is the structure of a liner. It is a set of points endowed with a family of subsets called lines. This family should satisfy two axioms, one of which is the first Euclid axiom postulating that any distinct points ...

Velocity Increment on Incidence Angle near the Leading Edge of the Compressor Cascade
Aerospace, 2023 The geometry of a compressor leading edge has an important effect on the aerodynamic performance at an off-designed incidence angle. The current geometric design methods of the leading edge are usually developed based on the flow characteristics at the ...

EFFICIENT SPATIO-TEMPORAL MODELLING TO ENABLE TOPOLOGICAL ANALYSIS [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 Time-dependent analysis scenarios such as heat, wind or flood analysis in cities and in landscapes need a correct and consistent modelling of geometry and topology over time.
