A remark on generalized complete intersections [PDF]

open access: yesNuclear Physics B, 2017
We observe that an interesting method to produce non-complete intersection subvarieties, the generalized complete intersections from L. Anderson and coworkers, can be understood and made explicit by using standard Cech cohomology machinery.

On complete intersections [PDF]

open access: yesAnnales de l'Institut Fourier, 2001
We construct closed complex submanifolds of dimension three in C^5 which are differential complete intersections but not holomorphic complete intersections.

(Open) packing number of some graph products [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
The packing number of a graph $G$ is the maximum number of closed neighborhoods of vertices in $G$ with pairwise empty intersections. Similarly, the open packing number of $G$ is the maximum number of open neighborhoods in $G$ with pairwise empty ...

Polarized Rigid Del Pezzo Surfaces in Low Codimension

open access: yesMathematics, 2020
We provide explicit graded constructions of orbifold del Pezzo surfaces with rigid orbifold points of type ki×1ri(1,ai):3≤ri≤10,ki∈Z≥0 as well-formed and quasismooth varieties embedded in some weighted projective space.

Which Schubert varieties are local complete intersections? [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We characterize by pattern avoidance the Schubert varieties for $\mathrm{GL}_n$ which are local complete intersections (lci). For those Schubert varieties which are local complete intersections, we give an explicit minimal set of equations cutting out ...

New Codes Arising from Complete (k, n)- arcs in PG(3,17) [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2023
The main aim of this work is to find new codes arising from construct a complete (k , n) – arcs in PG( 3,17), when n = 3,4,5 we take the union of some (k,n) – arcs.

Reinforcement Learning-Based Autonomous Driving at Intersections in CARLA Simulator

open access: yesSensors, 2022
Intersections are considered one of the most complex scenarios in a self-driving framework due to the uncertainty in the behaviors of surrounding vehicles and the different types of scenarios that can be found.

AUTOMATIC DETECTION AND RECOGNITION OF ROAD INTERSECTIONS FOR ROAD EXTRACTION FROM IMAGERY [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Automatic road extraction from remote sensing imagery is very useful for many applications involved with geographic information. For road extraction of urban areas, road intersections offer stable and reliable information for extraction of road network ...
