Joint equidistributions of mesh patterns 123 and 321 with symmetric and minus-antipodal shadings
Shuzhen Lv, Philip B. Zhang
In this paper, we extend recent results by Lv and Kitaev by proving 20 (out of 22 possible) joint equidistributions of mesh patterns 123 and 321 with symmetric shadings, as well as…

Joint equidistributions of mesh patterns 123 and 132 with minus antipodal shadings
Shuzhen Lv, Philip B. Zhang
The study of joint equidistributions of mesh patterns 123 and 132 with the same symmetric shadings was recently initiated by Kitaev and Lv, where 75 of 80 potential joint equidistr…
