| dc.description | We introduce a method of constructing a forcing along a simplified $(κ,1)$-morass such that the forcing satisfies the $κ$-chain condition. Alternatively, this may be seen as a method to thin out a larger forcing to get a chain condition. As an application, we construct a ccc forcing that adds an $ω_2$-Suslin tree. Related methods are Shelah's historic forcing and Todorcevic's $ρ$-functions. | |
