For many purposes (e.g., for the study of moduli spaces of Langlands parameters), it is desirable to have a theory of families of disconnected reductive groups. In this talk, I will describe some elements of such a theory and give applications.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><u>Tuesday, June 06 2023<o:p></o:p></u></b></p><p class=MsoNormal><b>Special Year Research Seminar<o:p></o:p></b></p><p class=MsoNormal><b>Topic: </b>On Dynamics of B-free Systems Generated by Behrend Sets<o:p></o:p></p><p class=MsoNormal><b>Speaker: </b>Stanislaw Kasjan - Nicolaus Copernicus University <o:p></o:p></p><p class=MsoNormal><b>Time/Room: </b>02:00 PM - 03:00 PM / Simonyi 101 and Remote Access<o:p></o:p></p><p class=MsoNormal><b>Zoom Link: </b><a href="https://theias.zoom.us/j/85880175827?pwd=SWYwdnl0eDJkK1hrQnRSNkN5ZnBhQT09">https://theias.zoom.us/j/85880175827?pwd=SWYwdnl0eDJkK1hrQnRSNkN5ZnBhQT09</a><o:p></o:p></p><p class=MsoNormal><b>Abstract URL: </b><a href="https://www.ias.edu/math/events/special-year-research-seminar-18">https://www.ias.edu/math/events/special-year-research-seminar-18</a><o:p></o:p></p><p class=MsoNormal><b><o:p> </o:p></b></p><p class=MsoNormal><b><u>Friday, June 09 2023<o:p></o:p></u></b></p><p class=MsoNormal><b>Milnor Conjecture Learning Seminar<o:p></o:p></b></p><p class=MsoNormal><b>Topic: </b>TBD<o:p></o:p></p><p class=MsoNormal><b>Speaker: </b>TBA<o:p></o:p></p><p class=MsoNormal><b>Time/Room: </b>01:00 PM - 03:30 PM / Rubenstein Commons Meeting Room 5<o:p></o:p></p><p class=MsoNormal><b>Zoom Link: </b><a href="https://theias.zoom.us/j/87654714875?pwd=ZXl5QWVSRGRSd3JCMWVJczI0RUoxUT09">https://theias.zoom.us/j/87654714875?pwd=ZXl5QWVSRGRSd3JCMWVJczI0RUoxUT09</a><o:p></o:p></p><p class=MsoNormal><b>Abstract URL: </b><a href="https://www.ias.edu/math/events/milnor-conjecture-learning-seminar-19">https://www.ias.edu/math/events/milnor-conjecture-learning-seminar-19</a><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
