<p>I would like to ask what the specific novel model-theoretic (or set-theoretic) techniques, if any, are that Mochizuki uses in his recent series of four papers. Section 3 of Inter-universal Teichmüller Theory IV, as well as the comments on page 21 of paper I, seem to suggest that there are model-theoretic techniques in play; I don't, unfortunately, have the background in algebraic geometry to understand the presentation.</p>
