Per Alexandersson, Leonardo Saud Maia Leite
Unit interval graphs admit a classical Catalan encoding by area sequences, or equivalently by Dyck paths. We introduce a new statistic on these graphs, called peak-nesting, defined…

Real-rootedness and interlacing for parking functions and Chow polynomials
Per Alexandersson
We prove real-rootedness for the Chow polynomials of the noncrossing partition lattices by transferring tieless parking functions to finite-alphabet Smirnov words and applying an i…
