Monotone links in DAHA and EHA

Pavel Galashin, Thomas Lam

We define monotone links on a torus, obtained as projections of curves in the plane whose coordinates are monotone increasing. Using the work of Morton-Samuelson, to each monotone…

Braid variety cluster structures, II: general type

Pavel Galashin, Thomas Lam, Melissa Sherman-Bennett

We show that braid varieties for any complex simple algebraic group are cluster varieties. This includes open Richardson varieties inside the flag variety .

Effect of Boundary Conditions on Second-Order Singularly-Perturbed Phase Transition Models on

Thomas Lam

The second-order singularly-perturbed problem concerns the integral functional for a bounded open set $Ω\subsete…

Braid variety cluster structures, I: 3D plabic graphs

Pavel Galashin, Thomas Lam, Melissa Sherman-Bennett +1

We introduce -dimensional generalizations of Postnikov's plabic graphs and use them to establish cluster structures for type braid varieties. Our results include known clust…

Electrical networks and the Grove algebra

Yibo Gao, Thomas Lam, Zixuan Xu

We study the ring of regular functions on the space of planar electrical networks, which we coin the grove algebra. This algebra is an electrical analogue of the Plücker ring studi…

Plabic links, quivers, and skein relations

Pavel Galashin, Thomas Lam

We study relations between cluster algebra invariants and link invariants. First, we show that several constructions of positroid links (permutation links, Richardson links, grid d…
