Webrieties of cosingular complexes. In [9] Klein showed the variety of cosingular complexes in the generic case, i.e. for σ = [111111], is just the projective line. We show (see table 7.3) that the varieties of cosingular complexes are generically curves, except in one case. Finally, in the last section we reprove Klein’s result using our set up.
