Size-Dependent Properties of Miura-ori Tessellations

Chaewon Baek, Tomohiro Tachi, Jinkyu Yang, Hiromi Yasuda ยท 2026

We investigate the size-dependent behavior of Miura-ori-based origami tessellations by changing the number of origami unit cells. For large tessellations, the Miura-ori sheet generally exhibits a negaโ€ฆ

Bihamiltonian tests for integrable systems associated to rank-$1$ F-CohFTs

Alexandr Buryak, Jianghao Xu, Di Yang ยท 2026

Double ramification (DR) hierarchies associated to rank-$1$ F-CohFTs are important integrable perturbations of the Riemann--Hopf hierarchy. In this paper, we perform bihamiltonian tests for these DR hโ€ฆ
