Combinatorial characterzations of $T$ -designs in the nonbinary Johnson scheme

Hiroshi Nozaki, Yuta Watanabe

We study $T$ -designs in the nonbinary Johnson scheme. This scheme generalizes both the Johnson and Hamming schemes and admits a bivariate $Q$ -polynomial structure. Zhu (2021) provi…

Bigness of adjoint linear subsystem and approximation theorems with ideal sheaves on weakly pseudoconvex manifolds

Yuta Watanabe

Let $X$ be a weakly pseudoconvex manifold and $L ⟶ X$ be a holomorphic line bundle with a singular positive Hermitian metric $h$ . In this article, we provide a points…
