**If such successful seminars exist, I would love to hear the details how this works in practice; what do students speak about, their research or something else; are such seminars run by students themselves or by staff.**<p>

The Math Department of the University of Colorado at Boulder has a seminar like this, run by graduate students. To answer the question, ``What do students speak about'', let me copy a few of the recent titles (= Fall 2021).<p>
