Generalizing Kobayashi plus/minus Selmer groups for elliptic curves, B\\\"uy\\\"ukboduk and Lei have defined modified Selmer groups, called signed Selmer groups, for certain non-ordinary $\\mathrm{Gal}(\\overline{F}/F)$-representations. In particular, their construction applies to abelian varieties defined over $F$ with good supersingular reduction at primes of $F$ dividing $p$.
