We prove that it is consistent that the covering number of the ideal of measure zero sets has countable cofinality.
The notion of a chord diagram emerged from Vassiliev's work Vas90], Vas92] (see also Gusarov Gus91], Gus94] and Bar-Natan BN91], BN95]). Slightly later, Kontsevich Kon93] deened an invariant of classical knots taking values in the algebra generated by formal linear combinations of chord diagrams modulo the four-term relation. This knot invariant establishes an isomorphism of a projective limit ...
we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...
in this study, the relationship between teachers’ creative and critical thinking skills and their reflectivity in teaching was investigated. to this end, three questions were raised. these questions were intended to determine whether there was a significant relationship between teachers’ creative thinking skills and their reflectivity in teaching; whether there was a significant relationship be...
this study sought to examine the effect of cooperative game on iranian students achievements in english alphabet learning. cooperative games are games, in which players or teams work together towards a common goal without defeating someone. the methodology used in this study was experimental. the population of the study was 60 female students from the grade one in secondary school in tabriz, ir...
Mizaj (Temperament) is one of the basic concepts of Iranian Traditional Medicine (ITM), which has great importance in diagnosis and treatment of diseases, as well as maintaining the ideal healthy state of an individual. However, very little is known about the biological mechanisms of mizaj dependence treatment in practical ITM. This study was aimed to evaluate any association between the mizaj ...
We examine two different m-traces in the category of representations over quantum Lie superalgebra associated to sl(m|n) at root unity. The first m-trace is on ideal projective modules and leads new Extended Topological Quantum Field Theories. second perturbative typical modules. consider quotient with respect negligible morphisms coming from this show that case sl(2|1) 3-manifolds invariants. ...
The goal of this paper is to introduce methods that allow us to calculate certain limits and colimits in the category of modules over a principal ideal domain. We start with a quick review of basic categorical language and duality. Then we develop the concept of universal morphisms and derive limits and colimits as special cases. The completeness and cocompleteness theorems give us methods to c...
The relationship between ideals I of Turing degrees and groups of I{recursive automorphisms of the ordering on rationals is studied. We discuss the diierences between such groups and the group of all auto-morphisms, prove that the isomorphism type of such a group completely deenes the ideal I, and outline a general correspondence between principal ideals of Turing degrees and the rst{order prop...
