The minimal model program for deformations of Hilbert schemes of points on the projective plane
... The Hilbert scheme of points on an algebraic variety is the moduli space that parameterizes 0-dimensional subschemes of length n on the variety, with given positive integer n. In the case of curves, the Hilbert scheme of ...

Birational models of moduli spaces of coherent sheaves on the projective plane
... The birational geometry of moduli spaces of sheaves on surfaces has been studied a lot in recent years; see for instance Arcara, Bertram, Coskun and Huizenga [2], Bayer and Macrì [6; 7], Bertram, Martinez and Wang [9], ...

Bonnesen style inequalities on surfaces of constant curvature
... Many inequalities of style (1.2), called Bonnesen-style inequalities, were found along with variations and generalizations in the past decades [2, 5, 6, 8, 11, 19, 29–34]. On the other hand, the classical isoperimetric ...
