A Note concerning Veblen ' S Axioms for Geometry
Veblen has given a set of axioms for geometry.!. The first eight of these are as follows : % Axiom I. There exist at least two distinct points. Axiom II. If points A, B, C are in the order ABC, they are in the order CBA. Axiom III. If points A, B, C are in the order ABC, they are not in the order BCA. Axiom IV. If points A, B, C are in the order ABC, then A is distinct from C. Axiom V. If A and...

15 صفحه اولA Note on the Axioms for Zilber's Pseudo-Exponential Fields
We show that Zilber’s conjecture that complex exponentiation is isomorphic to his pseudo-exponentiation follows from the a priori simpler conjecture that they are elementarily equivalent. An analysis of the firstorder types in pseudo-exponentiation leads to a description of the elementary embeddings, and the result that pseudo-exponential fields are precisely the models of their common first-or...
متن کاملA Note on Axioms for Infinite-generic Structures
In this note we give some natural examples of theories T in countable logics L such that the class GT of infinite-generic structures for T is not axiomatizable by a single sentence of LW1> w. The point of the examples is to provide a contrast to a certain phenomenon recently observed in model-theory, concerning the assignment to L-theories T of classes GT of L-structures. In many interesting ca...
متن کاملa study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
