On -weakly cross -intersecting families for sets and vector spaces
Shuhui Yu, Lijun Ji
Let (resp. ) be an -element set (resp. -dimensional vector space over the finite field ), and (resp. )…
New results of Bollobás-type theorem for affine subspaces and projective subspaces
Shuhui Yu, Xin Wang
Bollobás-type theorem has received a lot of attention due to its application in graph theory. In 2015, Gábor Heged{ü}s gave an upper bound of bollobás-type affine subspace families…
-almost -intersecting families for vector spaces
Shuhui Yu, Lijun Ji
Let be a family of -dimensional subspaces of an -dimensional vector space. Write $\mathcal{D}_{\mathcal{F}}(H;t)=\{F\in \mathcal{F}\colon \dim(F\cap H)\leq t \}…
-almost -intersecting families for vector spaces
Lijun Ji, Dehai Liu, Kaishun Wang +2
Let be a finite dimensional vector space over a finite field, and a family consisting of -subspaces of . The family is called -intersecting…
Construction of optimal flag codes by MRD codes
Shuangqing Liu, Shuhui Yu, Lijun Ji
Flag codes have received a lot of attention due to its application in random network coding. In 2021, Alonso-González et al. constructed optimal -Optimum distance…
New constructions of cyclic subspace codes
Shuhui Yu, Lijun Ji
A subspace of a finite field is called a Sidon space if the product of any two of its nonzero elements is unique up to a scalar multiplier from the base field. Sidon spaces, introd…
