On the Mazur--Tate refined conjecture for the anticyclotomic tower at inert primes

Ryota Shii

Let $E$ be an elliptic curve defined over $Q$ with supersingular reduction at $p \geq 5$ , and $K$ be an imaginary quadratic field such that $p$ is inert in $K / Q$ .…

The 2-adic valuations of the algebraic central $L$ -values for quadratic twists of weight 2 newforms

Taiga Adachi, Keiichiro Nomoto, Ryota Shii

Let $f$ be a normalized newform of weight 2 on $Γ_{0} (N)$ whose coefficients lie in $Q$ and let $χ_{M}$ be a primitive quadratic Dirichlet character with conductor $M$ . In thi…

On non-trivial $Λ$ -submodules with finite index of the plus/minus Selmer group over anticyclotomic $Z_{p}$ -extension at inert primes

Ryota Shii

Let $K$ be an imaginary quadratic field where $p$ is inert. Let $E$ be an elliptic curve defined over $K$ and suppose that $E$ has good supersingular reduction at $p$ . In this pape…
