On the Iwasawa invariants of Kato's zeta elements for modular forms
Chan-Ho Kim, Jaehoon Lee, Gautier Ponsinet
We study the behavior of the Iwasawa invariants of the Iwasawa modules which appear in Kato's main conjecture without -adic -functions under congruences. It generalizes the w…

The structure of Selmer groups and the Iwasawa main conjecture for elliptic curves
Chan-Ho Kim
We reveal a new and refined application of (a weaker statement than) the Iwasawa main conjecture for elliptic curves to the structure of Selmer groups of elliptic curves of arbitra…
