S4A1 Graduate Seminar Algebraic Geometry (Friday Seminar), Winter term 2026/27, 4-6pm, SR 0.006

<br>
<br>
<br>
We will cover three topics this term:
<br>
<br>
1. Dynamics (Cat(0), Cremona, etc.), 
<br>2. Brauer groups (recent results of Scavia-Reichstein),
<br> 3. Moduli spaces and hyperholomorphic bundles
<br>
<br>
<br>

Students are encouraged to participate. Either by giving talks or by attending the talks
and surveying one or two of the talks at the end of term to obtain credit points.
<br>Please get in touch huybrech@math.uni-bonn.de.
