Isomorphism problems of noncommutative deformations of type $D$ Kleinian singularities [PDF]
, 2009 We construct all possible noncommutative deformations of a Kleinian singularity ${\mathbb C}^2/\Gamma$ of type $D_n$ in terms of generators and relations, and solve the isomorphism problem for the associative algebras thus constructed.

A note on the polynomial approximation of vertex singularities in the boundary element method in three dimensions [PDF]
, 2008 We study polynomial approximations of vertex singularities of the type $r^\lambda |\log r|^\beta$ on three-dimensional surfaces. The analysis focuses on the case when $\lambda > -\frac 12$.

Singularities of noncommutative surfaces [PDF]
, 2018 The primary objects of study in this thesis are noncommutative surfaces; that is, noncommutative noetherian domains of GK dimension 2. Frequently these rings will also be singular, in the sense that they have infinite global dimension.

Deformations of functions and F-manifolds [PDF]
, 2004 We study deformations of functions on isolated singularities. A unified proof of the equality of Milnor and Tjurina numbers for functions on isolated complete intersections singularities and space curves is given.

Del Pezzo Singularities and SUSY Breaking
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.

Tjurina and Milnor numbers of matrix singularities [PDF]
, 2005 To gain understanding of the deformations of determinants and Pfaffians resulting from deformations of matrices, the deformation theory of composites f ◦ F with isolated singularities is studied, where f : Y −→C is a function with (possibly non-isolated)

Yang–Baxter deformations, AdS/CFT, and twist-noncommutative gauge theory
Nuclear Physics B, 2016 We give an AdS/CFT interpretation to homogeneous Yang–Baxter deformations of the AdS5×S5 superstring as noncommutative deformations of the dual gauge theory, going well beyond the canonical noncommutative case.

Recent Developments in Instantons in Noncommutative ℝ𝟒
Advances in Mathematical Physics, 2010 We review recent developments in noncommutative deformations of instantons in ℝ4. In the operator formalism, we study how to make noncommutative instantons by using the ADHM method, and we review the relation between topological charges and ...

N $$ \mathcal{N} $$ = 1 conformal dualities from unoriented chiral quivers
Journal of High Energy Physics, 2022 We study various orientifold projections of 4d N $$ \mathcal{N} $$ = 1 toric gauge theories, associated with CY singularities known as L a,b,a /ℤ2, with a + b even. We obtain superconformal chiral theories that have the same central charge, anomalies and

Vector perturbations of Kerr-AdS5 and the Painlevé VI transcendent
Journal of High Energy Physics, 2020 We analyze the Ansatz of separability for Maxwell equations in generically spinning, five-dimensional Kerr-AdS black holes. We find that the parameter μ introduced in [1] can be interpreted as apparent singularities of the resulting radial and angular ...
