A Formalist Analysis of Mohtasham Kashani’s Tarkib-band Based on Form and Meaning Point of View

Mohtasham Kashani, the great elegist of Islamic World, revolutionized the form of elegies with his famous Tarkib-band, in a way that no other poet has ever done so before and after him. One of the main concerns of this study is analyzing the relation between the inner and outer form of his poems. After analyzing the contents of his Tarkib-band, we reach to this fact that, there is a strong conn...

Dirac theory from a field theoretic point of view

Several complications arise in quantum field theory because of the infinite many degrees of freedom. However, the distinction between one-particle and many-particle effects – mainly induced by the vacuum – is not clear up to now. A field theoretic picture of the one-particle Dirac theory is developed in order to explore such questions. Main emphasis is laid on the injection of Grassmann’s algeb...

Acyclic Cluster Algebras from a Ring Theoretic Point of View

The article gives a ring theoretic perspective on cluster algebras. Geiß-Leclerc-Schröer prove that all cluster variables in a cluster algebra are irreducible elements. Furthermore, they provide two necessary conditions for a cluster algebra to be a unique factorization domain, namely the irreducibility and the coprimality of the initial exchange polynomials. We present a sufficient condition f...

Constructing Regular Ultrafilters from a Model-theoretic Point of View

This paper contributes to the set-theoretic side of understanding Keisler’s order. We consider properties of ultrafilters which affect saturation of unstable theories: the lower cofinality lcf(א0,D) of א0 modulo D, saturation of the minimum unstable theory (the random graph), flexibility, goodness, goodness for equality, and realization of symmetric cuts. We work in ZFC except when noted, as se...
