Cohen Forcing with Fra\"iss\'e Classes Beyond $\aleph_1$
Kostana [5] asked for natural conditions on a class $\mathcal{K}$ to ensure that forcing with finite members of $\mathcal{K}$ on an underlying set $X$ is forcing equivalent to Cohen forcing. We show that if $\mathcal{K}_{\triangle}$ is the class of finite triangle-free graphs and $|X|\geq\aleph_2$, then $ \mathbb{C}_X(...
