Iustin Coanda, Guenther Trautmann
We show that the idea used by Kempf (1990) in order to obtain a splitting criterion for vector bundles on projective spaces leads to an elementary proof of the Babylonian tower the…

On the moduli scheme of stable sheaves supported on cubic space curves
Hans-Georg Freiermuth, Guenther Trautmann
We investigate the geometry of the Simpson moduli space M of stable sheaves on P_3 with Hilbert polynomial H(m)=3m+1 and describe explicitly the two smooth, rational components, th…
