TitlePicturing flags
PresenterArun Ram (The University of Melbourne)
Author(s)Dr Arun Ram

What is a flag variety? A lattice? A projective space? The Veblen-Young theorem?
Cosets? Subspaces? A building? A simplicial complex? A generalised generalised
quadrangle? An incidence geometry? A Chevalley group? Borel subalgebras? Borel
subgroups? The LUP factorisation?  The Bruhat decomposition? The Schubert
calculus?  A polarization? A twisted Chevalley group? An isotropic subsapce? An
ovoid? A finite simple group? Perhaps the right answer is in the title of
Wassily Kandinsky’s book, POINT AND LINE TO PLANE.
