Abstract: Banderier, Marchal and Wallner considered Young tableaux with walls, which are similar to standard Young tableaux, except that local decreases are allowed at some walls. In this work, we prove a conjecture of Fuchs and Yu concerning the enumeration of two classes of three-row Young tableaux with walls. Combining with the work by Chang, Fuchs, Liu, Wallner and Yu leads to the verification of a conjecture on phylogenetic tree-child networks proposed by Pons and Batle. This talk is based on joint work with Feihu Liu, Jiahang Liu, Jing Liu and Guoce Xin.
