Admissible Pairs vs Gieseker--Maruyama
Nadezda V. Timofeeva
A morphism of the moduli functor of admissible semistable pairs to the Gieseker -- Maruyama moduli functor (of semistable coherent torsion-free sheaves) with the same Hilbert polyn…

Elementary proof of reducedness of Hilbert schemes of points in higher dimensions
Nadezda Timofeeva
The criterion for an affine primary algebra over the field to be integral, is proven. Using this criterion we give a simple proof that Hilbert scheme of 0-dimensional subschemes of…

Infinifesimal Criterion for Flatness of Projective Morphism of Schemes
Nadezda V. Timofeeva
The generalisation of the well-known (Hilbert polynomial) criterion for flatness of a projective morphism of Noetherian schemes is given for the case of nonreduced base of the morp…
