On the Iwasawa theory of Cayley graphs

This paper explores Iwasawa theory from a graph theoretic perspective, focusing on the algebraic and combinatorial properties of Cayley graphs. Using representation theory, we analyze Iwasawa-theoretic invariants within Z_-towers of Cayley graphs, revealing connections between graph theory, number theory, and group theory. Key results include the factorization of associated Iwasawa polynomials and the decomposition of μ- and λ-invariants. Additionally, we apply these insights to complete graphs, establishing conditions under which these invariants vanish.
