Editorial Volume 6, Issue 1

The editor’s notes in our Journal have been so far a site for the clarification of the Journal’s policy and the task still continues. With an inclination towards solving our real world problems in language teaching (and literary studies, which I will discuss in the next issue of the Journal), we would like to take that the introduction of the concept of “life-world” to Social Sciences can be a ...

$n$-cocoherent rings‎, ‎$n$-cosemihereditary rings and $n$-V-rings

 Let $R$ be a ring‎, ‎and let $n‎, ‎d$ be non-negative integers‎. ‎A right $R$-module $M$ is called $(n‎, ‎d)$-projective if $Ext^{d+1}_R(M‎, ‎A)=0$ for every $n$-copresented right $R$-module $A$‎. ‎$R$ is called right $n$-cocoherent if every $n$-copresented right $R$-module is $(n+1)$-coprese-nted‎, ‎it is called a right co-$(n,d)$-ring if every right $R$-module is $(n‎, ‎d)$-projective‎. ‎$R$...

6 v 1 1 1 Ju n 19 93 Cosmic Voids and Biased Galaxy Formation

Using cosmological N -body simulations and the void probability function (VPF), we investigate the statistical properties of voids within a wide range of initially Gaussian models for the origin of large-scale structure. We study the dependence of the VPF on cosmological parameters, on the power spectrum of primordial fluctuations, and on assumptions about galaxy formation. We pay particular at...
