Ideal class monoids of cubic orders

Sungmun Cho, Jungtaek Hong, Yuchan Lee

Let $R$ be an order in a number field, let $Cl (R)$ be its ideal class monoid, and let $Cl (R)$ act on it by multiplication. The local-global product for…

Beyond Endoscopy for $GL_{3} (Q)$ : Functional equation for the $L$ -function of a cubic order

Yuchan Lee

The Beyond Endoscopy strategy, proposed by Langlands, aims to establish the principle of functoriality by analyzing the trace formula. Recently, Deng and Espinosa advanced this pro…
