Characterizing immutable sandpiles: A first look

چکیده
By working with coefficients in Z or R, one can define two different notions of stability for a sandpile on graph. We call immutable when these agree. Our main results give linear-algebraic characterizations large classes sandpiles.

Immutable Objects in Java
Immutability is a very useful and desirable property for objects. This paper investigates different possible notions of immutability for Java objects, to find out which notion is the most intuitive and useful, both when it comes to ways of enforcing immutability of objects, and when it comes to exploiting information about (im)mutability of objects in program verification and in various static ...
متن کاملLadder Sandpiles
We study Abelian sandpiles on graphs of the form G×I, where G is an arbitrary finite connected graph, and I ⊂ Z is a finite interval. We show that for any fixed G with at least two vertices, the stationary measures μI = μG×I have two extremal weak limit points as I ↑ Z. The extremal limits are the only ergodic measures of maximum entropy on the set of infinite recurrent configurations. We show ...
متن کاملPeer-Reviewed, Publishable Hypertexts: A First Look
Despite the fact the hypermedia has long been discussed as a suitable format for academic research publications, the academic community has made little progress toward realizing hypermedia publishing. In this paper, we provide an initial framework for considering the problems facing any system designed for publishing academic hypertexts, and propose some first steps our community can take towar...
متن کاملA first look at blazars with BeppoSAX
The ”blazar phenomenon” is due to the presence of relativistic flows (jets) emanating from the nuclei of active galaxies which are radio loud. The power to energize the radio lobes is transported in the jets. Blazars are the subset of radio loud AGN for which the relativistic jet happens to point at small angles to the line of sight. Since the radiation emitted by the jet is relativistically be...
متن کاملLayered, Multivariate Anomaly Explanations: A First Look
An anomaly is a data point that deviates dramatically from some set of related data points, based on some common metric. For instance, consider the flights shown in Table 1. In this table, flights 2 and 5 are anomalous because their flying time is much longer than the average even though the set of airports is similar. While there is significant research on finding anomalous records within data...
