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 ... 
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 ... 
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 ... 
The efficiency of the semidirect products of free abelian monoid with rank n by the ınfinite cyclic monoid
(Amer Inst Physics, 2011)In this paper we give necessary and sufficient conditions for the efficiency of the semidirect product of free abelian monoid with rank n by the infinite cyclic monoid. 
The minimal polynomials of 2cos(pi/2k) over the rationals
(Amer Inst Physics, 2011)The number lambda(q) = 2cos pi/q, q is an element of N, q >= 3, appears in the study of Hecke groups which are Fuchsian groups of the first kind, and in the study of regular polyhedra. Here we obtained the minimal polynomial ... 
Neutrosophic soft deltatopology and neutrosophic soft compactness
(Amer Inst Physics, 2019)We introduce the concepts of neutrosophic soft deltainterior, neutrosophic soft quasicoincidence, neutrosophic soft qneighborhood, neutrosophic regular open soft set, neutrosophic soft deltaclosure, neutrosophic soft ... 
Neutrosophic soft preseparation axioms
(Amer Inst Physics, 2019)In this study, we introduce the concept of neutrosophic soft preopen (neutrosophic soft preclosed) sets and preseparation axioms in neutrosophic soft topological spaces. In particular, the relationship between these ... 
Neutrosophic soft semiregularization topologies andneutrosophic soft submaximal spaces
(Amer Inst Physics, 2019)In this study, we aim to investigate the neutrosophic soft semiregularization spaces associated with neutrosophic soft topological spaces. We introduce the concept of neutrosophic soft submaximal spaces and prove that ... 
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. 
New numerical techniques for solving fractional partial differential equations in conformable sense
(Springer, 2019)This study adresses two new numerical techniques for solving some interesting onedimensional timefractional partial differential equations (PDEs). We have introduced modified homotopy perturbation method in conformable ... 
On m*  gclosed sets and m*  R0 spaces in a hereditary mspace (X, m, H)
(Amer Inst Physics, 2019)Noiri and Popa [18] have defined the minimal local function and the minimal structure m(H)* which contains m in a hereditary minimal space (X, m, H). Moreover the concepts of m  Hg  closed sets and (A, m(H)*)closed ... 
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.
