Del Pezzo Singularities and SUSY Breaking [PDF]
Advances in High Energy Physics, 2011 An analytic construction of compact Calabi-Yau manifolds with del Pezzo singularities is found. We present complete intersection CY manifolds for all del Pezzo singularities and study the complex deformations of these singularities.

Deformations of Toric Singularities and Fractional Branes [PDF]
Journal of High Energy Physics, 2006 Fractional branes added to a large stack of D3-branes at the singularity of a Calabi-Yau cone modify the quiver gauge theory breaking conformal invariance and leading to different kinds of IR behaviors.

Deformations of Log Terminal and Semi Log Canonical Singularities
Forum of Mathematics, Sigma, 2023 In this paper, we prove that klt singularities are invariant under deformations if the generic fiber is $\mathbb {Q}$ -Gorenstein. We also obtain a similar result for slc singularities. These are generalizations of results of Esnault-Viehweg [Math.

Deformation of singular foliations, 1: Local deformation cohomology [PDF]
Comptes Rendus. Mathématique, 2020 In this paper we introduce the notion of deformation cohomology for singular foliations and related objects (namely integrable differential forms and Nambu structures), and study it in the local case, i.e., in the neighborhood of a point.

Journal of High Energy Physics, 2022 Compactification of M-theory and of IIB string theory on threefold canonical singularities gives rise to superconformal field theories (SCFTs) in 5d and 4d, respectively.

The Poincaré Index on Singular Varieties
J, 2022 In this paper, we discuss a few simple methods for computing the local topological index and its various analogs for vector fields and differential forms given on complex varieties with singularities of different types.

Deformation of singular lagrangian subvarieties [PDF]
Mathematische Annalen, 2003 We investigate deformations of lagrangian manifolds with singularities. We introduce a complex similar to the de Rham-complex whose cohomology calculates deformation spaces. Examples of singular lagrangian varieties are presented and deformations are calculated explicitly.

On Multivariate Picard–Fuchs Systems and Equations
J, 2023 In this paper, we studied the Picard–Fuchs systems and equations which appear in the theory of Gauss–Manin systems and connections associated with deformations of isolated singularities. Among other things, we describe some interesting properties of such

Rank-two 5d SCFTs from M-theory at isolated toric singularities: a systematic study
Journal of High Energy Physics, 2020 We carry out a detailed exploration of the deformations of rank-two five-dimensional superconformal field theories (SCFTs) T X $$ {\mathcal{T}}_{\mathbf{X}} $$ , which are geometrically engineered by M-theory on the space transverse to isolated toric ...
