Let k be a field, R a k-algebra and A = R[θ1, θ2, . . . , θn] a PoincaréBirkhoff-Witt extension of R. If each θi acts locally finitely on R, then we show that GKdim(A) = GKdim(R) + n. From this we deduce some results concerning incomparability, prime length and Tauvel’s height formula in the crossed product R?g where g is a finite-dimensional Lie algebra acting as derivations on R. Similar resu...
chapter two presents three m-admissible function algebras ab, bd, and sl, to construct the universal abelian, band, and semilattice compactifications, respectively. the main results are (11.3), (12.3), and (12.4). some inclusion relationships between these function algebras and the other well-known ones, presented in section 8, are made via the devico of compactifications. chpter three is about...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
tomato (l.ycopersicon esculentum mill.) cv. rio grande seedlings were nutritionally conditioned with solutions complete fertilizer n(60% no3+40% nh4)-p-k (20-20-20) , n(30%no3+70% nh4)-p-k (15-5-30) , the first two week n(60% no3+40% nh4)-p-k (20-20-20) and later two week n(30%no3+70% nh4)-p-k (15-5-30) and vice versa were applied in completely randomized experiment with three replicat...
cognitive studies of translation process have recently been awarded a great deal of attention. there exists a psychological angle to almost all translation activities. the present study, thus, deals with analysing the relationships between iranian prospective translators tolerance for ambiguity (ta) and their willingness to translate (wtt). the research was conducted as a mixed methods study, d...
Let S be a surface in P2 × P2 given by the intersection of a (1,1)form and a (2,2)-form. Then S is a K3 surface with two noncommuting involutions σx and σy . In 1991 the second author constructed two height functions ĥ+ and ĥ− which behave canonically with respect to σx and σy , and in 1993 together with the first author showed in general how to decompose such canonical heights into a sum of lo...
the mordell-weil theorem states that the group of rational points on an elliptic curve over the rational numbers is a finitely generated abelian group. in our previous paper, h. daghigh, and s. didari, on the elliptic curves of the form $ y^2=x^3-3px$, bull. iranian math. soc. 40 (2014), no. 5, 1119--1133., using selmer groups, we have shown that for a prime $p$...
the aim of the current study was to investigate the relationship among efl learners learning style preferences, use of language learning strategies, and autonomy. a total of 148 male and female learners, between the ages of 18 and 30, majoring in english literature and english translation at islamic azad university, central tehran were randomly selected. a package of three questionnaires was ad...
Fix the data (p,K,E) where p is a prime number, K a number field, and E an elliptic curve over Q. Let K∞/K denote the maximal Zp-power extension of K. Recent work provides, in some instances, detailed information about p-adic completions of Mordell-Weil groups and their associated p-adic height pairings, and the p-primary Shafarevich-Tate groups and their associated Cassels pairings, over inter...
