DESCRIPTION:Raymond Cheng (Leibniz Universität Hannover)\nLet’s count: 
 1\, 2\, q+1. The eponymous objects are special projective hypersurfaces of
  degree q+1\, where q is a power of the positive ground field characterist
 ic. This talk will sketch an analogy between the geometry of q-bic hypers
 urfaces and that of quadric and cubic hypersurfaces. For instance\, the mo
 duli spaces of linear spaces in q-bics are smooth and themselves have rich
  geometry. In the case of q-bic threefolds\, I will describe an analogue o
 f result of Clemens and Griffiths\, which relates the intermediate Jacobia
 n of the q-bic with the Albanese of its surface of lines.
