Superconformal Field Theory on Threebranes at a Calabi-Yau Singularity [PDF]
Nuclear Physics B, 1998 Just as parallel threebranes on a smooth manifold are related to string theory on $AdS_5\times {\bf S}^5$, parallel threebranes near a conical singularity are related to string theory on $AdS_5\times X_5$, for a suitable $X_5$.

Morita theory and singularity categories [PDF]
, 2020 We propose an analogue of the bounded derived category for an augmented ring spectrum, defined in terms of a notion of Noether normalization. In many cases we show this category is independent of the chosen normalization.

Singularity Theory for W-Algebra Potentials [PDF]
, 1993 The Landau potentials of $W_3$-algebra models are analyzed with algebraic-geometric methods. The number of ground states and the number of independent perturbations of every potential coincide and can be computed. This number agrees with the structure of

Confinement in (1 + 1) dimensions: a holographic perspective from I-branes
Journal of High Energy Physics, 2023 In this paper we holographically study the strongly coupled dynamics of the field theory on I-branes (D5 branes intersecting on a line). In this regime, the field theory becomes (2 + 1) dimensional with 16 supercharges.

Loop Quantum Black Hole Extensions Within the Improved Dynamics
Frontiers in Astronomy and Space Sciences, 2021 We continue our investigation of an improved quantization scheme for spherically symmetric loop quantum gravity. We find that in the region where the black hole singularity appears in the classical theory, the quantum theory contains semi-classical ...

T T ¯ $$ T\overline{T} $$ , black holes and negative strings
Journal of High Energy Physics, 2020 String theory on AdS3 has a solvable single-trace irrelevant deformation that is closely related to T T ¯ $$ T\overline{T} $$ . For one sign of the coupling, it leads to an asymptotically linear dilaton spacetime, and a corresponding Hagedorn spectrum ...

Articulating assemblage theory for salient urban atmospheres in children’s environments
Ain Shams Engineering Journal, 2021 In using the assemblage theory, this article focuses on the concepts of “city singularity” and “urban atmospheres” in designing better places for children.

Bounce Universe with Finite-Time Singularity
Universe, 2022 This work explains how the presence of a Type-IV singularity (a mild singularity) can influence the dynamics of a bouncing universe. In particular, we examine the bounce cosmology that appears with a Type-IV singularity in the context of a ghost-free ...

Singularity development and supersymmetry in holography
Journal of High Energy Physics, 2017 We study the effects of supersymmetry on singularity development scenario in holography presented in [1] (BBL). We argue that the singularity persists in a supersymmetric extension of the BBL model. The challenge remains to find a string theory embedding

A holographic kaleidoscope for N $$ \mathcal{N} $$ = 1*
Journal of High Energy Physics, 2019 We study in detail the recently-found family of asymptotically AdS5 × S 5 type IIB supergravity solutions dual to the N $$ \mathcal{N} $$ = 1* SYM theory with equal masses.
