The kernel of a rational Eisenstein prime at non-squarefree level

Hwajong Yoo

Let $ℓ \geq 5$ be a prime and let $N$ be a non-squarefree integer not divisible by $ℓ$ . For a rational Eisenstein prime $m$ of the Hecke ring $T (N)$ of le…

Abelian arithmetic Chern-Simons theory and arithmetic linking numbers

Hee-Joong Chung, Dohyeong Kim, Minhyong Kim +3

Following the method of Seifert surfaces in knot theory, we define arithmetic linking numbers and height pairings of ideals using arithmetic duality theorems, and compute them in t…
