A dynamic system approach for solving nonlinear programming problems with exact penalty function
(Vilnius Gediminas Technical Univ Press, 2008)The Dynamic system has attracted increasing attention in recent years. In this paper, a dynamic system approach for solving Nonlinear Programming (NLP) problems with inequality constrained is presented. First, the system ... -
On spherical product surfaces in E3
(2009)In the present study we consider spherical product surfaces X = α⊗β of two 2D curves in E3. We prove that if a spherical product surface patch X = α⊗β has vanishing Gaussian curvature K (i.e. a flat surface) then either α ... -
Primes in z[exp(2 pi i/3)]
(Amer Inst Physics, 2010)In this paper, we study the primes in the ring Z[w], where w = exp(2 pi i/3) is a cubic root of unity. We gave a classification of them and some results related to the use of them in the calculation of cubic residues are obtained. -
Rewriting as a special case of noncommutative grobner bases theory for the affine weyl group ((a)over tilde(n))
(Birkhauser Boston, 2010)The aim of this work is to find Grobner-Shirshov bases of the affine Weyl group of type (A(n)) over tilde (n >= 2) from the point of complete rewriting systems. -
On the norms of toeplitz and hankel matrices with pell numbers
(Amer Inst Physics, 2010)Let us define A = [a(ij)](i,j=0)(n-1) and B = [b(ij)](i,j=0)(n-1) as n x n Toeplitz and Hankel matrices, respectively, such that a(ij) = Pi-j and b(ij) = Pi+j, where P denotes the Pell number. We present upper and lower ... -

(Amer Inst Physics, 2010)In this paper the Estrada index of Hermite matrix is firstly defined and investigated. In fact this is a natural generalization of Estrada, distance Estrada and Laplacian Estrada indices. Thus all properties about them can ... -
A new example of deficiency one groups
(Amer Inst Physics, 2010)The main purpose of this paper is to present a new example of deficiency one groups by considering the split extension of a finite cyclic group by a free abelian group having rank two. -

Determination of genus of normal subgroups of discrete groups
(Amer Inst Physics, 2010)In this work, subgroups of a special class of discrete subgroups of PLS(2, R), namely the ones of the first kind with genus 0, have been studied. We establish a technique to compute the genus of these subgroups in terms ... -

(Amer Inst Physics, 2011)In this paper we give necessary and sufficient conditions for the efficiency of the semi-direct product of free abelian monoid with rank n by the infinite cyclic monoid. -
Conjugacy for free groups under split extensions
(Amer Inst Physics, 2011)At the present paper we show that conjugacy is preserved and reflected by the natural homomorphism defined from a semigroup S to a group G, where G defines split extensions of some free groups. The main idea in the proofs ... -

Sequential definitions of fuzzy continuity in fuzzy spaces
(Amer Inst Physics, 2019)Cakalli extended the concept of G-sequential compactness to a fuzzy topological group and introduced the notion of G-fuzzy sequential compactness, where G is a function from a suitable subset of the set of all sequences ...
