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...
