Abstract
AbstractFor a graph $$\Gamma $$
Γ
, let K be the smallest field containing all eigenvalues of the adjacency matrix of $$\Gamma $$
Γ
. The algebraic degree $$\deg (\Gamma )$$
deg
(
Γ
)
is the extension degree $$[K:\mathbb {Q}]$$
[
K
:
Q
]
. In this paper, we completely determine the algebraic degrees of Cayley graphs over abelian groups and dihedral groups.
