Functorial stratifications of singularities in characteristic 0

Vicente Monreal

We prove that the riso-stratifications of singularities of affine algebraic sets introduced by Bradley-Williams--Halupczok are embedding independent and can be computed Ã©tale loca…

Classification of Horikawa surfaces with T-singularities

Vicente Monreal, Jaime Negrete, Giancarlo UrzÃºa

We classify all projective surfaces with only T-singularities, ample canonical class, and $K^{2} = 2 p_{g} - 4$ . In this way, we identify all surfaces, smoothable or not, with only T-singul…
