Shelah's stability spectrum and homogeneity spectrum in finite diagrams
We present Saharon Shelah's Stability Spectrum and Homogeneity Spectrum theorems, as well as the equivalence between the order property and instability in the framework of Finite Diagrams. Finite Diagrams is a context which generalizes the first order case. Localized versions of these theorems are presented. Our presentation is based on several papers; the point of view is contemporary and some...
متن کاملStability of the spectrum
For piecewise expanding one-dimensional maps without periodic turning points we prove that isolated eigenvalues of small (random) perturbations of these maps are close to isolated eigenvalues of the unperturbed system. (Here “eigenvalue” means eigenvalue of the corresponding Perron-Frobenius operator acting on the space of functions of bounded variation.) This result applies e.g. to the approxi...
متن کاملSimulation Spectrum and Stability Models
In this paper, we define a continuum of modeling styles, ranging from collections of very simple agents on one end to collections of very complex agents at the other end, and a simulation support mechanism that makes them all interoperable with ordinary discrete event simulation programs (at the simulation level; application-domain interoperability is harder). We show how all of these simulatio...
متن کاملAchieving Simultaneous Spectrum Utilization and Revenue Improvements in Practical Wireless Spectrum Auctions
Spectrum is a valuable, scarce and finite natural resource that is needed for many different applications, so efficient use of the scarce radio spectrum is important for accommodating the rapid growth of wireless communications. Spectrum auctions are one of the best-known market-based solutions to improve the efficiency of spectrum use. However, Spectrum auctions are fundamentally differen...
متن کاملNotes on the Stability Spectrum
I wrote this document while preparing for my qualifying exam in model theory. The goal was to clarify for myself some of the many equivalent definitions that appear in stability theory, including where countable language assumptions are necessary, and to collect the arguments that go into Shelah’s stability spectrum for countable theories in a compact, readable, and hopefully memorable form. In...
