Block designs with $g cd (r, λ) = 1$ admitting flag-transitive automorphism groups

Seyed Hassan Alavi, Mohsen Bayat, Mauro Biliotti +12

In this paper, we present a classification of $2$ -designs with $g cd (r, λ) = 1$ admitting flag-transitive automorphism groups. If $G$ is a flag-transitive automorphism group of a non-…

On the explicit constructions of certain unitary $t$ -designs

Eiichi Bannai, Mikio Nakahara, Da Zhao +1

Unitary $t$ -designs are `good' finite subsets of the unitary group $U (d)$ that approximate the whole unitary group $U (d)$ well. Unitary $t$ -designs have been applied in randomized…

Half of an antipodal spherical design

Eiichi Bannai, Da Zhao, Lin Zhu +2

We investigate several antipodal spherical designs on whether we can choose half of the points, one from each antipodal pair, such that they are balanced at the origin. In particul…
