Information Operators in Categorical Information Spaces

open access: yesInformation, 2010
The general theory of information (GTI) is a synthetic approach, which reveals the essence of information, organizing and encompassing all main directions in information theory.

Loopwise Route Representation-Based Topology Optimization for the Shortest Path Problems

open access: yesIEEE Access, 2022
This study investigates the analogy between the electric circuit and roadway traffic analyses based on the loop-wise route representation (LRR). These two seemingly different fields share common aspects in terms of primitive components, system behavior ...

Mathematical Models of Abstract Systems: Knowing abstract geometric forms [PDF]

open access: yes, 2013
Scientists use models to know the world. It i susually assumed that mathematicians doing pure mathematics do not. Mathematicians doing pure mathematics prove theorems about mathematical entities like sets, numbers, geometric figures, spaces, etc., they ...

Orbit categories, classifying spaces, and generalized homotopy fixed points [PDF]

open access: yes, 2017
We give a new description of Rosenthal's generalized homotopy fixed point spaces as homotopy limits over the orbit category. This is achieved using a simple categorical model for classifying spaces with respect to families of subgroups.Comment: 10 pages.

2-Group Representations for Spin Foams [PDF]

open access: yes, 2009
Just as 3d state sum models, including 3d quantum gravity, can be built using categories of group representations, "2-categories of 2-group representations" may provide interesting state sum models for 4d quantum topology, if not quantum gravity. Here we

The evolution of representation in simple cognitive networks [PDF]

open access: yes, 2013
Representations are internal models of the environment that can provide guidance to a behaving agent, even in the absence of sensory information. It is not clear how representations are developed and whether or not they are necessary or even essential ...

A geometry of information, I: Nerves, posets and differential forms [PDF]

open access: yes, 2005
The main theme of this workshop (Dagstuhl seminar 04351) is `Spatial Representation: Continuous vs. Discrete'. Spatial representation has two contrasting but interacting aspects (i) representation of spaces' and (ii) representation by spaces.

General Characteristics for Poisoning-Induced Transient or Sustained Hyperammonemia

open access: yesJournal of the Korean society of clinical toxicology, 2016
Purpose: In patients with altered mentality caused by drugs or unknown causes, ammonia is checked to facilitate differential diagnosis or diagnose hepatic coma. This helps early prevention and treatment of brain damage due to hyperammonemia.

Twenty-five years of two-dimensional rational conformal field theory [PDF]

open access: yes, 2009
In this article we try to give a condensed panoramic view of the development of two-dimensional rational conformal field theory in the last twenty-five years.Comment: A review for the 50th anniversary of the Journal of Mathematical Physics.
