Congruence properties of the coefficients of the classical modular polynomials

Haiyang Wang

The classical modular polynomials $Φ_{ℓ} (X, Y)$ give plane curve models for the modular curves $X_{0} (ℓ) / Q$ and have been extensively studied. In this article, we provide…

On the Kodaira types of elliptic curves with potentially good supersingular reduction

Haiyang Wang

Let $O_{K}$ be a Henselian discrete valuation domain with field of fractions $K$ . Assume that $O_{K}$ has algebraically closed residue field $k$ . Let $E / K$ be an el…

Explicit Witt basis over the tensor product of Clifford algebras and octonions

Yong Li, Guangbin Ren, Haiyan Wang

In this article, we investigate how the Witt basis serves as a link between real and complex variables in higher-dimensional spaces. Our focus is on the detailed construction of th…
