When is the ring of real measurable functions a hereditary ring?
Let $M(X, mathcal{A}, mu)$ be the ring of real-valued measurable functions on a measure space $(X, mathcal{A}, mu)$. In this paper, we characterize the maximal ideals in the rings of real measurable functions and as a consequence, we determine when $M(X, mathcal{A}, mu)$ is a hereditary ring.
متن کاملWhen every $P$-flat ideal is flat
In this paper, we study the class of rings in which every $P$-flat ideal is flat and which will be called $PFF$-rings. In particular, Von Neumann regular rings, hereditary rings, semi-hereditary ring, PID and arithmetical rings are examples of $PFF$-rings. In the context domain, this notion coincide with Pr"{u}fer domain. We provide necessary and sufficient conditions for...
متن کاملNeuronal microtubules: when the MAP is the roadblock.
Recent studies shed new light on a potential cascade of events by which neurological diseases such as Alzheimer's lead to axonal degeneration. In this model, the pathology starts with an elevation in microtubule-associated proteins (MAPs) such as tau. This renders the microtubules less accessible to motor proteins, which impairs their capacity to sustain anterograde axonal transport of proteins...
متن کاملWhen the Map Is Better Than the Territory
The causal structure of any system can be analyzed at a multitude of spatial and temporal scales. It has long been thought that while higher scale (macro) descriptions of causal structure may be useful to observers, they are at best a compressed description and at worse leave out critical information. However, recent research applying information theory to causal analysis has shown that the cau...
متن کاملEconomic-Statistical Design of a Control Chart for High Yield Processes When the Inspection is Imperfect
CCC-r control chart is a monitoring technique for high yield processes. It is based on the analysis of the number of inspected items until observing a specific number of defective items. One of the assumptions in implementing CCC-r chart that has a significant effect on the design of the control chart is that the inspection is perfect. However, in reality, due to the multiple reasons, the...
