As a mathematician, my dream is to help make progress on and be alive to see Goldbach’s Conjecture proof [ecstatic emoji here]!

Counting Metaplectic Ice and Modified Alternating Sign Matrices

Abstract: Mills, Robbins, and Rumsey conjectured that for a given n, there exists (1!7!...(3n-2)!)/(n!(n+1)!...(2n-1)!) alternating sign matrices (ASM). Zeilberger proved the conjecture by establishing a bijection between ASMs and totally symmetric self-plane partitions. Kuperberg provided a second proof using the bijection between ASMs and ice models with domain wall boundary conditions. We introduce modified alternating sign matrices, and we prove a bijection with modified boundary conditions for the ice models. Furthermore, we modify Kuperberg's proof to provide a count for certain sizes of modified alternating sign matrices.
