Ternary universal sums of generalized polygonal numbers

Jangwon Ju, Byeong-Kweon Oh, Bangnam Seo

An integer of the form $p_{m} (x) = \frac{( m - 2 ) x ^{2} - ( m - 4 ) x}{2} (m \geq 3)$ , for some integer $x$ is called a generalized polygonal number of order $m$ . A ternary sum $Φ_{i,j,k}^{a,b,c}(…

Spinor representations of positive definite ternary quadratic forms

Jangwon Ju, Kyoungmin Kim, Byeong-Kweon Oh

For a positive definite integral ternary quadratic form $f$ , let $r (k, f)$ be the number of representations of an integer $k$ by $f$ . The famous Minkowski-Siegel formula implies tha…

Genus-correspondences respecting spinor genus

Jangwon Ju, Byeong-Kweon Oh

For two positive definite integral ternary quadratic forms $f$ and $g$ and a positive integer $n$ , if $n \cdot g$ is represented by $f$ and $n \cdot d g = df$ , then the pair $(f, g)$ is…

A generalization of Watson transformation and representations of ternary quadratic forms

Jangwon Ju, Inhwan Lee, Byeong-Kweon Oh

Let $L$ be a positive definite (non-classic) ternary $\z$-lattice and let $p$ be a prime such that a $\frac 12\z_p$-modular component of $L_{p}$ is nonzero isotropic and $4 \cdot d L$ …
