Balázs Keszegh: An improved lower bound on the induced saturation problem for posets

Abstract:
I will present a result of Andrea Freschi, Simón Piga, Maryam Sharifzadeh, Andrew Treglown (https://arxiv.org/abs/2207.03974), showing that the induced poset saturation function sat*(n,P) is either bounded or at least 2sqrt(2n-2), which improves the previous lower bound of logn considerably.
