Affine groups as flag-transitive and point-primitive automorphism groups of symmetric designs

Seyed Hassan Alavi, Mohsen Bayat, Ashraf Daneshkhah +1

In this article, we investigate symmetric designs admitting a flag-transitive and point-primitive affine automorphism group. We prove that if an automorphism group $G$ of a symmetr…

Practical Synchronization for OTFS

Mohsen Bayat, Sanoopkumar P. S., Arman Farhang

In the existing literature on joint timing and frequency synchronization of orthogonal time frequency space modulation (OTFS), practically infeasible impulse pilot with large peak-…

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-…

Almost simple groups of Lie type and symmetric designs with $λ$ prime

Seyed Hassan Alavi, Mohsen Bayat, Ashraf Daneshkhah

In this article, we investigate symmetric $(v, k, λ)$ designs $D$ with $λ$ prime admitting flag-transitive and point-primitive automorphism groups $G$ . We prove that if $G$ …

Flag-transitive block designs and unitary groups

Seyed Hassan Alavi, Mohsen Bayat, Ashraf Daneshkhah

In this article, we study $2$ -designs with $g cd (r, λ) = 1$ admitting a flag-transitive automorphism group. The automorphism groups of these designs are point-primitive of almost sim…

Flag-transitive block designs with prime replication number and almost simple groups

Seyed Hassan Alavi, Mohsen Bayat, Jalal Choulaki +1

In this article, we study $2$ -designs with prime replication number admitting a flag-transitive automorphism group. The automorphism groups of these designs are point-primitive of…

Symmetric designs and four dimensional projective special unitary groups

Seyed Hassan Alavi, Mohsen Bayat, Asharf Daneshkhah +1

In this article, we study symmetric $(v, k, λ)$ designs admitting a flag-transitive and point-primitive automorphism group $G$ whose socle is $P S U_{4} (q)$ . We prove that there exis…

Finite exceptional groups of Lie type and symmetric designs

Seyed Hassan Alavi, Mohsen Bayat, Ashraf Daneshkhah

In this article, we study symmetric $(v, k, λ)$ designs admitting a flag-transitive and point-primitive automorphism group $G$ whose socle $X$ is a finite simple exceptional group…
