A Lattice is a partially ordered set where both least upper bound and greatest lower bound of any pair of elements are unique and exist within the set. Kötter and Kschischang proved that codes in the linear lattice can be used for error and erasure-correction in random networks. Codes in the linear lattice have previously been shown to be special cases of codes in modular lattices. Two well known classifications of modular lattices are geometric and distributive lattices. We have identified the… Expand

Coding for Errors and Erasures in Random Network Coding
TLDR
A Reed-Solomon-like code construction, related to Gabidulin's construction of maximum rank-distance codes, is described and a Sudan-style ldquolist-1rdquo minimum-distance decoding algorithm is provided. Expand
The Lattice Structure of Linear Subspace Codes
TLDR
It is proved that a linear code in a projective space forms a sublattice of the corresponding projective lattice if and only if the code is closed under intersection. Expand

TLDR
It is shown that the conjecture that the largest cardinality of a linear subspace code in Pq(n) is 2n holds forlinear subspace codes that are closed under intersection, i.e., codes having the property that the intersection of any pair of codewords is also a codeword. Expand
Equidistant Linear Codes in Projective Spaces
TLDR
It is established that the problem of finding equidistant linear codes of maximum size in Pq(n) with constant distance 2d is equivalent to the problems of finding the largest d-intersecting family of subspaces in GQ(n, 2d) for all 1 ≤ d ≤ bn2 c. Expand
Johnson Type Bounds for Mixed Dimension Subspace Codes
TLDR
Improved upper bounds for subspace codes in random linear network coding are given based on the Johnson bound for constant dimension codes. Expand

Distributivity for Upper Continuous and Strongly Atomic Lattices
TLDR
It is proved that an upper continuous and strongly atomic lattice is distributive if and only if it satisfies (D) and ($$\hbox {D}^*$$D∗) which are strengthenings of Birkhoff's conditions. Expand
A note on equidistant subspace codes
TLDR
A classification of the largest 1-intersecting codes in PG ( 5 , 2 ) , whose codewords are planes, is provided and new constructions of large equidistant codes are presented. Expand
