Exceptional collections of line bundles on projective homogeneous
varieties
The existence question for full exceptional collections in the bounded
derived category of coherent sheaves of a smooth projective variety
X goes back to the foundational results of Beilinson and BernsteinGelfandGelfand
when X is the projective space. The works of Kapranov in 80's suggested
that the structure of projective homogeneous variety on X should imply
the existence of full exceptional collections. We construct new examples
of exceptional collections of line bundles on the variety of Borel
subgroups of a split semisimple linear algebraic group G of rank 2
over a field. We exhibit exceptional collections of the expected length
for Dynkin types A2 and B2=C2 and prove that no such collection exists
for type G2. This settles the question of the existence of full exceptional
collections of line bundles on projective homogeneous Gvarieties
for split linear algebraic groups G of rank at most 2.
This is a report on the joint paper with A.Ananyevskiy, A.Auel and
S.Garibaldi.
