Galois geometries and coding theory are two research areas which have been interacting
with each other for many decades. From the early examples linking linear MDS codes with …

Improved bounds and singleton-optimal constructions of locally repairable codes with minimum distance 5 and 6

B Chen, W Fang, ST **a, J Hao… - IEEE Transactions on …, 2020 - ieeexplore.ieee.org
Repair locality has been an important metric in a distributed storage system (DSS). Erasure
codes with small locality are more popular in a DSS, which means fewer available nodes …

[HTML][HTML] Flag codes from planar spreads in network coding

C Alonso-González, MÁ Navarro-Pérez… - Finite Fields and Their …, 2020 - Elsevier
In this paper we study a class of multishot network codes given by families of nested

Constructions of constant dimension codes

AL Horlemann-Trautmann, J Rosenthal - Network Coding and Subspace …, 2018 - Springer
Constant dimension codes are subsets of the finite Grassmann variety. The subspace
distance is a natural metric on the Grassmannian. It is desirable to have constructions of …

Optimum distance flag codes from spreads via perfect matchings in graphs

C Alonso-González, MÁ Navarro-Pérez… - Journal of Algebraic …, 2021 - Springer
In this paper, we study flag codes on the vector space F _q^ n F qn, being qa prime power
and F _q F q the finite field of q elements. More precisely, we focus on flag codes that attain …

Constructions and bounds for subspace codes

S Kurz - arxiv preprint arxiv:2112.11766, 2021 - arxiv.org
Subspace codes are the $ q $-analog of binary block codes in the Hamming metric. Here the
codewords are vector spaces over a finite field. They have eg applications in random linear …

[HTML][HTML] Equidistant subspace codes

E Gorla, A Ravagnani - Linear Algebra and its Applications, 2016 - Elsevier
In this paper we study equidistant subspace codes, ie subspace codes with the property that
each two distinct codewords have the same distance. We provide an almost complete …

Distributed storage systems based on intersecting subspace codes

N Raviv, T Etzion - 2015 IEEE International Symposium on …, 2015 - ieeexplore.ieee.org
Distributed storage systems based on intersecting constant dimension (equidistant) codes
are presented. These intersecting codes are constructed using the Plücker embedding …

Construction of a Class of Real Array Rank Distance Codes

NS Babu, B Ravivarma, EM Elsayed… - Journal of Electrical …, 2023 - Wiley Online Library
Rank distance codes are known to be applicable in various applications such as distributed
data storage, cryptography, space time coding, and mainly in network coding. Rank distance …

Bounds and constructions of singleton-optimal locally repairable codes with small localities

W Fang, R Tao, FW Fu, B Chen… - IEEE Transactions on …, 2024 - ieeexplore.ieee.org
An-locally repairable code (LRC) is called a Singleton-optimal LRC if it achieves the
Singleton-type bound. Analogous to the classical MDS conjecture, the maximal length …
