Stability conditions on blowups [PDF]

open access: yesarXiv
We study the relation between perverse stability conditions and geometric stability conditions under blow up. We confirm a conjecture of Toda in some special cases and show that geometric stability conditions can be induced from perverse stability conditions from semiorthogonal decompositions associated to blowups.

Hyers-Ulam Stability of Unbounded Closable Operators in Hilbert Spaces

open access: yes
In this paper, we discuss the Hyers-Ulam stability of closable (unbounded) operators with several interesting examples. We also present results pertaining to the Hyers-Ulam stability of the sum and product of closable operators to have the Hyers-Ulam ...

On the Selection Stability of Stability Selection and Its Applications [PDF]

open access: yesarXiv
Stability selection is a widely adopted resampling-based framework for high-dimensional structure estimation and variable selection. However, the concept of 'stability' is often narrowly addressed, primarily through examining selection frequencies, or 'stability paths'.

Spaces of stability conditions [PDF]

open access: yesarXiv, 2006
Stability conditions are a mathematical way to understand $\Pi$-stability for D-branes in string theory. Spaces of stability conditions seem to be related to moduli spaces of conformal field theories. This is a survey article describing what is currently known about spaces of stability conditions, and giving some pointers for future research.

Quantum Stochastic Stability [PDF]

open access: yesarXiv, 2009
the stability criterion is constructed for open quantum systems which govern by quantum stochastic differential equations (QSDE) both for quantum observable flow and the stochastic density operator. We derive stability criteria (local, asymptotic and exponential stability) for those QSDE.

On Hyers-Ulam Stability for Nonlinear Differential Equations of nth Order

open access: yesInternational Journal of Analysis and Applications, 2013
This paper considers the stability of nonlinear differential equations of nth order in the sense of Hyers and Ulam. It also considers the Hyers-Ulam stability for superlinear Emden-Fowler differential equation of nth order. Some illustrative examples are

On the Geometry of Stabilizer States [PDF]

open access: yesQuantum Information and Computation (QIC), vol. 14, no. 7-8, pp. 683-720, 2014, 2017
Large-scale quantum computation is likely to require massive quantum error correction (QEC). QEC codes and circuits are described via the stabilizer formalism, which represents stabilizer states by keeping track of the operators that preserve them. Such states are obtained by stabilizer circuits (consisting of CNOT, Hadamard and Phase gates) and can be
