Counting Alternating Sign Matrices and TSSCPPs: A Survey |
In the early 1980s, David Robbins along with Howard Rumsey and Bill Mills
conjectured that the number of n × n alternating sign matrices is
In the 1990s, through the efforts of many people, both of these conjectures were proven. In this talk, I will give a brief (and probably biased) survey of the paths taken to prove these conjectures. I will not assume that the audience has any familiarity with either of these conjectures or the terms involved. |
