Subgroup Perfect Codes in Bi-Cayley Graphs
Masoumeh Koohestani, Nasrin Soltankhah, Mohsen Ghasemi
In this paper, we study perfect codes in bi-Cayley graphs, focusing on when two subgroups and of a group G can form a perfect code of the form . We first cons…
Total perfect codes in Cayley sum graphs of cyclic groups
Masoumeh Koohestani, Doost Ali Mojdeh, Mohsen Ghasemi
We consider Cayley sum graphs over the cyclic group and aim to explore several necessary and sufficient conditions for the existence of total perfect codes in these…
Some results on perfect codes in Cayley sum graphs
Masoumeh Koohestani, Doost Ali Mojdeh, Mohsen Ghasemi +1
We establish a necessary and sufficient condition for a normal subgroup of a finite group to be a subgroup perfect code.
Scaling Limits for the Gibbs States on Distance-Regular Graphs with Classical Parameters
Masoumeh Koohestani, Nobuaki Obata, Hajime Tanaka
We determine the possible scaling limits in the quantum central limit theorem with respect to the Gibbs state, for a growing distance-regular graph that has so-called classical par…
On Characters of a Class of P-polynomial table algebras and applications
Masoumeh Koohestani, Amir Rahnamai Barghi, Amirhossein Amiraslani
In this paper, we study the characters of homogeneous monotonic P-polynomial table algebras with finite dimension d>=5. We then apply them to association schemes. To this end, we d…
The Application of Tridiagonal Matrices in P-polynomial Table Algebras
Masoumeh Koohestani, Amir Rahnamai Barghi, Amirhossein Amiraslani
In this paper, we study the characters of two classes of P-polynomial table algebras using tridiagonal matrices. To this end, we obtain some results about the eigen-structure of sp…
