Algebra and Logic Seminar
19 August @ 13:00 - 14:30
An online session of the Algebra and Logic Seminar will be held on August 19, 2022 (Friday) at 1:00 pm (UTC+3).
A talk on:
Examples of non-reduced components of the Hilbert Scheme of smooth projective curves using ruled surfaces
will be delivered by Hristo Iliev (American University in Bulgaria and IMI-BAS, Bulgaria).
Abstract. Let Id,g,r be the union of irreducible components of the Hilbert scheme whose general points represent smooth irreducible non-degenerate curves of degree d and genus g in Pr. Using a family of curves found on ruled surfaces over smooth curves of genus γ, we show that for γ ≥ 7 and g ≥ 6γ+5 the scheme I2g−4γ+1,g,g−3γ+1 acquires a non-reduced component D′ such that dim T[X′]D′ = dimD′ + 1 for a general point [X′] ∈ D′.
