Stanley–Reisner-type degeneration conjecture for loop-model schemes
Stanley–Reisner-type degeneration conjecture for loop-model schemes
Let be a link pattern, let be a diagram of , let be the associated scheme, and let denote its fixed-connectivity part for a connectivity . For every crossing of , the relevant component is described by the equations and . Loop-model degeneration conjecture. There exists a (partial) Gröbner -equivariant degeneration of into an in-general-unreduced scheme whose components are indexed by noncrossing loop configurations of , with the components coming from indexed by loop configurations of connectivity ; each geometric component is given by the stated equations and has multiplicity . The conjecture refines the expected Stanley–Reisner degeneration by allowing nonreduced components, whose multiplicities account for the loop weight. The supplied text gives no resolution, so it remains open.
