Abstract
For an irregular pair (p,k), the Iwasawa λ-invariant of the 1-k component of the ideal class group of p-cyclotomic fields has been computed to be one by several people. In this talk I will introduce some basic facts related to their computation method. The I will introduce my ongoing work on the relation between λ=1 with the triviality of Selmer groups for its associated two-variable Hida families.
