In this talk I will provide a tutorial on those ideas, with special emphasis on the interplay between quantum geometry and optics by means of optical sum rules. From those sum rules, several quantum-geometric and topological inequalities can be inferred, whose physical content will be discussed.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>The seminar will also be broadcast on Zoom for those who cannot attend in person: <a href="https://videoconf-colibri.zoom.us/j/99896945682"><span style='color:windowtext;text-decoration:none'>https://videoconf-colibri.zoom.us/j/99896945682</span></a> <o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>We look forward to seeing you there!<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText><span lang=PT>Org.
