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…
