Distributions of Iwasawa $λ$ -invariants of $Z_{p}$ -towers over supersingular isogeny graphs

Taiga Adachi, Kosuke Mizuno, Ryosuke Murooka +1

A graph-theoretic analogue of Iwasawa theory, initiated by Gonet and Vallières, has attracted considerable interest in the study of Iwasawa invariants. On the other hand, for a pai…

Spanning trees and their relations in Galois covers

Kosuke Mizuno

This paper studies the relation among the number of spanning trees of intermediate graphs in a Galois cover, building on results for $(Z /2 Z)^{m}$ -covers previously…

Iwasawa theory for weighted graphs

Taiga Adachi, Kosuke Mizuno, Sohei Tateno

Let $p$ be a prime number and let $d$ be a positive integer. In this paper, we generalize Iwasawa theory for graphs initiated by Gonet and Vallières to weighted graphs. In particul…
