Moduli of plane sheaves supported on curves of low multiplicity

Maican, M (IMRA)
Tuesday 28 June 2011, 14:00-14:30

Seminar Room 1, Newton Institute


We will classify the Gieseker semi-stable sheaves on the complex projective plane with support of dimension one and multiplicity four, five and, in some cases, multiplicity six. We will give natural stratifications for their moduli spaces. The strata are defined by means of cohomological conditions and have concrete geometric descriptions.
