Linear preservers and quantum information science
TL;DR: In this article, it was shown that a linear map of the form φ: π: M{mn} \rightarrow M{n} can be found in the tensor space of positive integers if and only if there exists a unitary unitary π, V \in π such that π has the form $A\otimes B \mapsto U(\varphi_1(A) \otimes π(B))V), where π is either the identity map or the transposition map.

Graphs associated with matrices over finite fields and their endomorphisms
TL;DR: In this paper, the independence number, chromatic number, and clique number of a regular connected graph with diameter equal to min { m, n } were derived for finite fields.

Linear preservers and quantum information science
TL;DR: In this article, a survey of linear preserver problems and quantum information science is given, and the structure of linear maps leaving invariant the spectral radius of matrices in tensor form A,⊗ B is also obtained.

Digraphs that have at most one walk of a given length with the same endpoints
Zejun Huang,Xingzhi Zhan +1 more
TL;DR: It is proved that if n>=5 and k>=n-1 then @q(n,k)=n( n-1)/2 and this maximum number is attained at D if and only if D is a transitive tournament.

The Schur complements of γ-diagonally and product γ-diagonally dominant matrix and their disc separation
TL;DR: In this paper, the Schur-based iteration is proposed to solve large scale linear systems though reducing the order by Schur complement and can compute out the results faster, which can solve large-scale linear systems.
