Preliminary Notes on Galois Theory
Definition 1.1. Let E be a field. An automorphism of E is a (ring) isomorphism from E to itself. The set of all automorphisms of E forms a group under function composition, which we denote by AutE. Let E be a finite extension of a field F . Define the Galois group Gal(E/F ) to be the subset of AutE consisting of all automorphisms σ : E → E such that σ(a) = a for all a ∈ F . We write this last c...
متن کاملPreliminary Notes
Bombesin and eledoisin are both biologically active peptides derived from amphibian skin. They have been established to affect a variety of centrally mediated physiological processes in mammals (e.g. DeCaro, Micossi , Venturi, Brancati and Scarnati, 1974; Rivier and Brown, 1978), and may therefore be similar to or identical with endogenous mammalian neuropeptides. One prominent class of peptide...
متن کاملPreliminary Notes on Decentralized Auctions of Complements
This note was motivated by a feature of decentralized markets: usually there is no central coordination on the selling mechanisms of items owned by different individuals. Specifically, I analyze separate auctions of several items possibly followed by resale among bidders. These items are complements for some bidders and are initially owned by different individuals. Without central coordination,...
متن کاملNotes on the coati, Nasua nasua (Carnivora: Procyonidae) in an Atlantic forest area.
Although Nasua nasua is broadly distributed geographically and relatively common, it is still little studied. This paper reports observations of coatis in an Atlantic Forest area, the Parque Estadual Carlos Botelho (PECB) in São Paulo State, Brazil. The social structure of coatis at PECB seems to be the same related in the literature. The mating season appears to be August-September and the pup...
