Stability in asymptotically AdS spaces [PDF]

open access: yesJournal of High Energy Physics, 2005
We discuss two types of instabilities which may arise in string theory compactified to asymptotically AdS spaces: perturbative, due to discrete modes in the spectrum of the Laplacian, and non-perturbative, due to brane nucleation. In the case of three dimensional Einstein manifolds, we completely characterize the presence of these instabilities, and in

Active Damping Adaptive Controller for Grid-Connected Inverter Under Weak Grid

open access: yesIEEE Access, 2021
The stability of grid-connected inverters is very sensitive to varying grid impedance, especially in the weak grid condition. In this paper, based on the Lyapunov method and with the micro-grid impedance identification, an active damping adaptive control

Strong K-stability and Asymptotic Chow-stability [PDF]

open access: yes, 2015
For a polarized algebraic manifold $(X,L)$, let $T$ be an algebraic torus in the group of all holomorphic automorphisms of $X$. Then strong relative K-stability will be shown to imply asymptotic relative Chow-stability. In particular, by taking $T$ to be trivial, we see that asymptotic Chow-stability follows from strong K-stability.

Asymptotic Stability Region of Slotted Aloha [PDF]

open access: yesIEEE Transactions on Information Theory, 2012
We analyze the stability of standard, buffered, slotted-Aloha systems. Specifically, we consider a set of $N$ users, each equipped with an infinite buffer. Packets arrive into user $i$'s buffer according to some stationary ergodic Markovian process of intensity $ _i$. At the beginning of each slot, if user $i$ has packets in its buffer, it attempts to

open access: yesProceedings of the American Mathematical Society, 1993
We consider a system of functional differential equation x ′ ( t ) = F ( t , x t ) {x’}(t) = F(t,{x_t}) and obtain conditions on a Liapunov functional to ensure the ...
