Streszczenie
We provide a relation between the $\mu $-invariants of the dual plus and minus Selmer groups for supersingular elliptic curves when we ascend from the cyclotomic ${\mathbb Z}_p$-extension to a ${\mathbb Z}_p^2$-extension over an imaginary quadratic field. Furthermore, we show that the (supersingular) $\mathfrak {M}_H(G)$-conjecture is equivalent to the statement that the $\mu $-invariant does not change as we go up the tower.
