Generic Characteristic-Zero Equivalence Between Derivative Bézout Inversion and Multipoint Evaluation

Zijian Zeng

Let $a_{1}, \dots, a_{m}$ be distinct elements of a field $K$ , and let $Z (X) = \prod_{i = 1}^{m} (X - a_{i})$ . We study the arithmetic complexity of computing the unique normalized Bezout pair $s…

Fixed Convex-Lens Spectral Constants: Möbius Reduction, Sharp Model Theorems, and Angle-Dependent Bounds

Zijian Zeng

For the intersection of two disks meeting at angle $2 α$ , let $C (α)$ be the least constant in the associated spectral-set inequality. We give a self-contained M"obius reduction to t…

A Counterexample to the Tang Zhang Schatten Norm Conjecture and Sharp Positive Results

Zijian Zeng, Houde Liu, Kurunathan Ratnavelu

For $m \geq 2$ , let $c_{p} (m)$ be the all-dimensional best constant in $k = 1 \sum m A_{k}_{p} \leq c_{p} (m) k = 1 \sum m ∣ A_{k} ∣_{p} .$ Tang and Zhang conjectur…
