Curve singularities with one Puiseux pair and value sets of modules over their local rings [PDF]
Journal of Algebraic Combinatoricsv3: Theorem 3.4 in v2 has been eliminated as a result of a gap in the proof. Section 3.2 in v2 has been eliminated. The rest of main results remain unchanged. General redaction has been improved. v1: Comments are very welcome! 19 pages.

Frobenius categories, Gorenstein algebras and rational surface singularities [PDF]
, 2014 We give sufficient conditions for a Frobenius category to be equivalent to the category of Gorenstein projective modules over an Iwanaga-Gorenstein ring.

Local analysis of Grauert-Remmert-type normalization algorithms [PDF]
, 2013 Normalization is a fundamental ring-theoretic operation; geometrically it resolves singularities in codimension one. Existing algorithmic methods for computing the normalization rely on a common recipe: successively enlarge the given ring in form an ...

Flops and Clusters in the Homological Minimal Model Program [PDF]
, 2017 Suppose that $f\colon X\to\mathrm{Spec}\, R$ is a minimal model of a complete local Gorenstein 3-fold, where the fibres of $f$ are at most one dimensional, so by [VdB1d] there is a noncommutative ring $\Lambda$ derived equivalent to $X$.

What Is the Validity Domain of Einstein’s Equations? Distributional Solutions over Singularities and Topological Links in Geometrodynamics [PDF]
, 2016 The existence of singularities alerts that one of the highest priorities of a centennial perspective on general relativity should be a careful re-thinking of the validity domain of Einstein’s field equations.

Singular projective varieties and quantization [PDF]
, 2000 By the quantization condition compact quantizable Kaehler manifolds can be embedded into projective space. In this way they become projective varieties. The quantum Hilbert space of the Berezin-Toeplitz quantization (and of the geometric quantization) is

Almost Conformal Vacua and Confinement [PDF]
, 2002 Dynamics of confining vacua which appear as deformed superconformal theory with a non-Abelian gauge symmetry, is studied by taking a concrete example of the sextet vacua of ${\cal N}=2$, SU(3) gauge theory with $n_f=4$, with equal quark masses.

Reconstruction algebras of type D (II) [PDF]
, 2013 This is the third in a series of papers which give an explicit description of the reconstruction algebra as a quiver with relations; these algebras arise naturally as geometric generalizations of preprojective algebras of extended Dynkin quivers.

Lectures on Mirror Symmetry [PDF]
, 1994 We give an introduction to mirror symmetry of strings on Calabi-Yau manifolds with an emphasis on its applications e.g. for the computation of Yukawa couplings.

Singularities of affine equidistants: projections and contacts [PDF]
, 2014 Using standard methods for studying singularities of projections and of contacts, we classify the stable singularities of affine $\lambda$-equidistants of $n$-dimensional closed submanifolds of $\mathbb R^q$, for $q\leq 2n$, whenever $(2n,q)$ is a pair ...
