First Steps towards Hyper-desingularization through Brauer-Severi Varieties
Raf Bocklandt, Stijn Symens, Geert Van de Weyer
Given a Cayley-Hamilton smooth order A in a central simple algebra , we determine the flat locus of the Brauer-Severi fibration of the smooth order. Moreover, we give a classifi…

Formal structures and representation spaces
Lieven Le Bruyn, Geert Van de Weyer
M. Kapranov introduced and studied in math.AG/9802041 the noncommutative formal structure of a smooth affine variety. In this note we show that his construction is a special case o…

Smooth Character Varieties for Torus Knot Groups
Jan Adriaenssens, Raf Bocklandt, Geert Van de Weyer
Semisimple representations of the free product Z_p*Z_q determine θ-semistable representations of a specific quiver Q_pq. The dimension vectors of θ-stable representations of this q…
