The universal zeta function for curve singularities and its relation with global zeta functions [PDF]

open access: yes, 2017
The purpose of this note is to give a brief overview on zeta functions of curve singularities and to provide some evidences on how these and global zeta functions associated to singular algebraic curves over perfect fields relate to each other.Comment ...

Curve singularities with one Puiseux pair and value sets of modules over their local rings [PDF]

open access: yesJournal of Algebraic Combinatorics
v3: 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.

Flops and Clusters in the Homological Minimal Model Program [PDF]

open access: yes, 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 $X$.

Almost Conformal Vacua and Confinement [PDF]

open access: yes, 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.

Singular projective varieties and quantization [PDF]

open access: yes, 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

Kleinian Singularities and the Ground Ring of C=1 String Theory [PDF]

open access: yes, 1992
We investigate the nature of the ground ring of c=1 string theory at the special A-D-E points in the c=1 moduli space associated to discrete subgroups of SU(2).

What Is the Validity Domain of Einstein’s Equations? Distributional Solutions over Singularities and Topological Links in Geometrodynamics [PDF]

open access: yes, 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.

Lectures on Mirror Symmetry [PDF]

open access: yes, 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.

Self-dual modules over local rings of curve singularities

open access: yesJournal of Pure and Applied Algebra, 2006
Let \(R\) be the complete local ring of a reduced curve singularity with residue field of characteristic \(0\). \(R\) is called of finite self-dual type if there exist only finitely many isomorphism classes of indecomposable, self-dual, torision-free \(R\)-modules.

The symmetric signature

open access: yes, 2016
We define two related invariants for a $d$-dimensional local ring $(R,\mathfrak{m},k)$ called syzygy and differential symmetric signature by looking at the maximal free splitting of reflexive symmetric powers of two modules: the top dimensional syzygy ...
