This inequality was conceived for a specific application that we will describe, but in the course of its investigation there were twists and turns that unearthed unexpected geometric phenomena and led to further applications to longstanding questions. These will be explained, but the main purpose of this talk is to show the geometric structures that arise in the proof. </span></p><p class="MsoPlainText" style="margin: 0in; text-align: start; -webkit-text-stroke-width: 0px;">	<span><span style="sans-serif"><span style="caret-color:#000000"><span style="color:#000000"><span style="font-style:normal"><span style="font-variant-caps:normal"><span style="font-weight:normal"><span style="letter-spacing:normal"><span style="orphans:auto"><span style="text-transform:none"><span style="white-space:normal"><span style="widows:auto"><span style="word-spacing:0px"><span style="-webkit-text-size-adjust:auto"><span style="text-decoration:none">Joint work with Robert Young</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></p><p>	 </p>
