Sinkhorn Linearization and the Spectral Proxy: Unifying the Statistical and Algorithmic Theory of Feature-Parameterized Inverse Optimal Transport via a Single Spectral Sandwich

Han Dong, Jiaming Li, Yongqiang Gong +2

We develop the statistical and algorithmic theory of inverse optimal transport (IOT) under the feature-parameterized cost C_theta(i,j) = -theta^T phi(i,j). The core technical contr…

Infinitely many elliptic curves over $Q (i)$ with rank 2 and $j$ -invariant 1728

Ben Savoie

We prove that there exist infinitely many elliptic curves over $Q (i)$ with $j$ -invariant $1728$ and rank exactly $2$ which are not obtained by base change from $\mathbb{Q}…

A graph-theoretic approach to computing Selmer groups of elliptic curves $y^{2} = x^{3} + b x$ over $Q (i)$

Anthony Kling, Ben Savoie

We develop a graph-theoretic algorithm to compute the $I ¨ $ -Selmer group of the elliptic curve $E_{b} : y^{2} = x^{3} + b x$ over $Q (i)$ , where $b \in Z [i]$ and $I ¨ $ is a…

Non-generic components of the Emerton-Gee stack for $GL_{2}$

Kalyani Kansal, Ben Savoie

Let $K$ be a finite unramified extension of $Q_{p}$ with $p > 3$ . We study the extremely non--generic irreducible components in the reduced part of the Emerton--Gee stack fo…
