Neat Rings
A ring is called clean if every element is the sum of a unit and an idempotent. Throughout the last 30 years several characterizations of commutative clean rings have been given. We have compiled a thorough list, including some new equivalences, in hopes that in the future there will be a better understanding of this interesting class of rings. One of the fundamental properties of clean rings i...
متن کاملGood things come in little packages: An introduction to writing .ins and .dtx files
LATEX packages made available from CTAN are commonly distributed as a pair of files: 〈something〉.ins and 〈something〉.dtx. The user is then instructed to run the .ins file through latex to produce the actual package files. What are these .ins and .dtx files? How do you, as a class or style-file writer, create your own? And, why would you want to? This article answers those questions and elucidat...
متن کاملSimAnt Simulation Using NEAT
In nature, ants in a colony often work together to complete a common task. We want to see if we can simulate this phenomenon. We create a simulation that looks at predator prey interactions based o↵ of the 1991 SimAnt game. In this game a spider attempts to eat individual ants from a colony, but if the ants form a large enough swarm they can work together to eat the spider. The question we are ...
متن کاملNeat Embeddings and Amalgamation
We present a property of neat reducts commuting with forming subalgebras as a definability condition. The purpose of this paper is to relate results on neat reducts, a notion particular to cylindric algebras to results on the “more universal” strong amalgamation property in a very general setting. It is known [7], [8] and [6] that amalgamation properties in a class of algebras correspond to int...
متن کاملNoisy Neurons, Neat Networks
In this issue of Neuron, Kiani et al. (2015) show that the correlated activity of multiple simultaneously recorded neurons can be used to identify, in a completely un-biased manner, distinct functional domains within prefrontal and (pre)motor cortex of macaque monkeys.
