Isogeny graphs on superspecial abelian varieties: Eigenvalues and Connection to Bruhat-Tits buildings

Yusuke Aikawa, Ryokichi Tanaka, Takuya Yamauchi

We study for each fixed integer $g \geq 2$ , for all primes $ℓ$ and $p$ with $ℓ \neq = p$ , finite regular directed graphs associated with the set of equivalence classes of $ℓ$ …

On Prym varieties for the coverings of some singular plane curves

Lubjana Beshaj, Takuya Yamauchi

Let $k$ be a field of characteristic zero containing a primitive $n$ -th root of unity. Let $C_{n}^{0}$ be a singular plane curve of degree $n$ over $k$ admitting an order $n$ automorph…
