Stability conditions
The stability of the inverse of the optimum forward prediction error filter obtained when the input data is nonstationary is investigated. Due to this nonstationary character, the resulting system (which is obtained assuming optimality on a sample-by-sample basis) is time-varying. It turns out that an extension of the Levinson recursion still provides a means to orderupdate the prediction error...
متن کاملI.I Stability Conditions
The conditions derived in section I.G are similar to the well known requirements for mechanical stability. A particle moving in an external potential U settles to a stable equilibrium at a minimum value of U . In addition to the vanishing of the force −U ′ , this is a consequence of the loss of energy to frictional processes. Stable equilibrium occurs at a minimum of the potential energy. For a...
متن کاملGluing Stability Conditions
We define and study a gluing procedure for Bridgeland stability conditions in the situation when a triangulated category has a semiorthogonal decomposition. As an application, we construct stability conditions on the derived categories of Z2-equivariant sheaves associated with ramified double coverings of P. Also, we study the stability space for the derived category of Z2-equivariant coherent ...
متن کاملComplementarity and stability conditions
Article history: Received 5 August 2016 Received in revised form 5 June 2017 Accepted 5 June 2017 Available online 8 June 2017 Editor: B. Grinstein We discuss the issue of complementarity between the confining phase and the Higgs phase for gauge theories in which there are no light particles below the scale of confinement or spontaneous symmetry breaking. We show with a number of examples that ...
