Crepant semi-divisorial log terminal model [PDF]
Épijournal de Géométrie Algébrique, 2021 We prove the existence of a crepant sdlt model for slc pairs whose irreducible components are normal in codimension one.

Which rational double points occur on del Pezzo surfaces? [PDF]
Épijournal de Géométrie Algébrique, 2021 We determine all configurations of rational double points that occur on RDP del Pezzo surfaces of arbitrary degree and Picard rank over an algebraically closed field $k$ of arbitrary characteristic ${\rm char}(k)=p \geq 0$, generalizing classical work of

Remark on complements on surfaces
Forum of Mathematics, Sigma, 2023 We give an explicit characterization on the singularities of exceptional pairs in any dimension. In particular, we show that any exceptional Fano surface is $\frac {1}{42}$ -lc.

Weighted Hodge ideals of reduced divisors
Forum of Mathematics, Sigma, 2023 We study the Hodge and weight filtrations on the localization along a hypersurface, using methods from birational geometry and the V-filtration induced by a local defining equation.

THE LIPMAN–ZARISKI CONJECTURE IN GENUS ONE HIGHER
Forum of Mathematics, Sigma, 2020 We prove the Lipman–Zariski conjecture for complex surface singularities with $p_{g}-g-b\leqslant 2$. Here $p_{g}$ is the geometric genus, $g$ is the sum of the genera of exceptional curves and $b$ is the first Betti number of the dual graph.

HODGE IDEALS FOR $\mathbb{Q}$-DIVISORS, $V$-FILTRATION, AND MINIMAL EXPONENT
Forum of Mathematics, Sigma, 2020 We compute the Hodge ideals of $\mathbb{Q}$-divisors in terms of the $V$-filtration induced by a local defining equation, inspired by a result of Saito in the reduced case. We deduce basic properties of Hodge ideals in this generality, and relate them to

Homogeneous Polynomials with Isomorphic Milnor Algebras [PDF]
, 2008 In Theorem 3.2 we show that two homogeneous polynomials $f$ and $g$ having isomorphic Milnor algebras are right-equivalent.Comment: 6 ...

A Classiffier for Unimodular Isolated Complete Intersection Space Curve Singularities
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016 C.T.C. Wall classified the unimodular complete intersection singularities. He indicated in the list only the μ-constant strata and not the complete classification in each case.

THE CHERN–SCHWARTZ–MACPHERSON CLASS OF AN EMBEDDABLE SCHEME
Forum of Mathematics, Sigma, 2019 The Chern–Schwartz–MacPherson class of a hypersurface in a nonsingular variety may be computed directly from the Segre class of the Jacobian subscheme of the hypersurface; this has been known for a number of years.

Two series of polyhedral fundamental domains for Lorentz bi-quotients [PDF]
, 2019 The main aim of this paper is to give two infinite series of examples of Lorentz space forms that can be obtained from Lorentz polyhedra by identification of faces.
