Permuted composition tableaux, 0-Hecke algebra and labeled binary trees
Vasu Tewari, Stephanie van Willigenburg
We introduce a generalization of semistandard composition tableaux called permuted composition tableaux. These tableaux are intimately related to permuted basement semistandard aug…
Necessary conditions for Schur-maximality
Foster Tom, Stephanie van Willigenburg
McNamara and Pylyavskyy conjectured precisely which connected skew shapes are maximal in the Schur-positivity order, which says that if is Schur-positive. To…
Resolving Stanley's -positivity of claw-contractible-free graphs
Samantha Dahlberg, Angele Foley, Stephanie van Willigenburg
In Stanley's seminal 1995 paper on the chromatic symmetric function, he stated that there was no known graph that was not contractible to the claw and whose chromatic symmetric fun…
Lollipop and lariat symmetric functions
Samantha Dahlberg, Stephanie van Willigenburg
We compute an explicit -positive formula for the chromatic symmetric function of a lollipop graph, . From here we deduce that there exist countably infinite distinct $e…
