題目： On iterated forcing with side conditions
アブストラクト： Aspero-Mota introduced an iterated forcing that used symmetric systems of elementary substructures with the markers. We reproduce it. Our construction features the following:
1. We stick to a single transitive set universe to form various clubs. 2. We use a pre-forced stationary set to manage amalgamations. 3. We use what we call signed coordinates rather than the markers.
We consider these features by iteratively forcing the following examples.
1. Posets that force what we call fast functions. 2. Posets that kill weak club guessings.
