Stability Conditions and Branes at Singularities [PDF]

, 2007
I use Bridgeland's definition of a stability condition on a triangulated category to investigate the stability of D-branes on Calabi-Yau cones given by the canonical line bundle over a del Pezzo surface.

Lyapunov-Induced Model Predictive Power Control for Grid-Tie Three-Level Neutral-Point-Clamped Inverter With Dead-Time Compensation

IEEE Access, 2019
In this paper, a new power control strategy based on a model predictive power control for the grid-tie three-level neutral point clamped inverter is presented.

Stability conditions and Kleinian singularities

, 2020
We describe the spaces of stability conditions on certain triangulated categories associated to Dynkin diagrams. These categories can be defined either algebraically via module categories of preprojective algebras, or geometrically via coherent sheaves ...

Scattering diagrams, Hall algebras and stability conditions [PDF]

Algebraic Geometry, 2016
To any quiver with relations we associate a consistent scattering diagram taking values in the motivic Hall algebra of its category of representations.

The co-stability manifold of a triangulated category [PDF]

, 2011
Stability conditions on triangulated categories were introduced by Bridgeland as a 'continuous' generalisation of t-structures. The set of locally-finite stability conditions on a triangulated category is a manifold which has been studied intensively ...

Stable Exact Solutions in Cosmological Models with Two Scalar Fields [PDF]

, 2010
The stability of isotropic cosmological solutions for two-field models in the Bianchi I metric is considered. We prove that the sufficient conditions for the Lyapunov stability in the Friedmann-Robertson-Walker metric provide the stability with respect ...

Mathematical Formulation of the No-Go Theorem in Horndeski Theory

Universe, 2019
We present a brief mathematical-like formulation of the no-go theorem, useful for bouncing and wormhole solutions in Horndeski theory. The no-go theorem is almost identical in the cases of flat FLRW geometry and static, spherically symmetric setting ...

Stability of high-entropy alloys under electrocatalytic conditions

iScience, 2023
Summary: High-entropy alloys are claimed to possess superior stability due to thermodynamic contributions. However, this statement mostly lies on a hypothetical basis.

Inducing stability conditions

, 2009
We study stability conditions induced by functors between triangulated categories. Given a finite group acting on a smooth projective variety we prove that the subset of invariant stability conditions embeds as a closed submanifold into the stability ...
