Total rings of quotients of higher dimensional Iwasawa algebras

Let $\mathcal G=H\rtimes\Gamma$ be a semidirect product of a finite group $H$ with $\Gamma=\mathbb Z_p^d$, the direct product of finitely many copies of the additive group of the $p$-adic integers. In the case $d=1$, Iwasawa algebras of such profinite groups were studied by Ritter--Weiss, Lau, Nickel, and the author. W...

Iwasawa theory of CM elliptic curves at potentially supersingular primes

We develop a plus and minus Iwasawa theory for CM elliptic curves with potentially supersingular reduction at a prime $p\ge5$. We construct local points that satisfy suitable"jumping trace"relations using the Honda--Demchenko theory applied to height-two formal groups over local fields with small ramification degree. T...
