Common fixed point theorems for two mappings in \(D^∗\)-metric spaces

JPRM-Vol. 1 (2008), Issue 1, pp. 132 – 142 Open Access Full-Text PDF
Shaban Sedghi, Nabi Shobe, Shahram Sedghi
Abstract: In this paper, we give some new definitions of \(D^∗\)-metric spaces and we prove a common fixed point theorem for two mappings under the condition of weakly compatible mappings in complete \(D^∗\)-metric spaces. We get some improved versions of several fixed point theorems in complete \(D^∗)-metric spaces.

On random covering of a circle

JPRM-Vol. 1 (2008), Issue 1, pp. 127 – 131 Open Access Full-Text PDF

Abstract: Let \(X_{j}\), \(j = 1, 2, …, n\) be the independent and identically distributed random vectors which take the values on the unit circumference. Let \(S_{n}\) be the area of the convex polygon having \(X_{j}\) as vertices. The paper by Nagaev and Goldfield (1989) has proved the asymptotic normality of random variableSn. Our main aim is to show that the random variableSn can be represented as a sum of functions of uniform spacings. This allows us to apply known results related to uniform spacings for the analysis of \(S_n\).

On the gracefulness of the digraphs \(n − C_{m}\) for \(m\) odd

JPRM-Vol. 1 (2008), Issue 1, pp. 118 – 126 Open Access Full-Text PDF
Zhao Lingqi, Jirimutu, Xirong Xu, Wang Lei
Abstract: A digraph D(V, E) is said to be graceful if there exists an injection \(f : V (G) → {0, 1, · · · , |E|}\) such that the induced function \(f’:E(G) → {1, 2, · · · , |E|}\) which is defined by \(f'(u, v) = [f(v)−f(u)] (mod |E|+1)\) for every directed edge \((u, v)\) is a bijection. Here, \(f\) is called a graceful labeling (graceful numbering) of \(D(V, E)\), while \(f’\) is called the induced edge’s graceful labeling of D. In this paper we discuss the gracefulness of the digraph \(n − C_{m}\) and prove that \(n − C_{m}\) is a graceful digraph for \(m = 5, 7, 9, 11, 13\) and even n.

Matrix lie rings that contain an abelian subring

JPRM-Vol. 1 (2008), Issue 1, pp. 113 – 117 Open Access Full-Text PDF
Evgenii L. Bashkirov
Abstract: Let \(k\) be a field and \(\overline{k}\) an algebraic closure of \(k\). The paper is devoted to the description of subrings of the Lie ring \(sl_{2}overline{k}\) that contain an abelian subring which is a one-dimensional subspace of the \(k\)-vector space \(sl_{2}overline{k}\).

Algebraic properties of special rings of formal series

JPRM-Vol. 1 (2007), Issue 1, pp. 178 – 185 Open Access Full-Text PDF
Azeem Haider
Abstract: The \(K\)-algebra \(K_{S}[[X]]\) of Newton interpolating series is constructed by means of Newton interpolating polynomials with coefficients in an arbitrary field K (see Section 1) and a sequence S of elements \(K\). In this paper we prove that this algebra is an integral domain if and only if \(S\) is a constant sequence. If K is a non-archimedean valued field we obtain that a \(K\)-subalgebra of convergent series of \(K_{S}[[X]]\) is isomorphic to Tate algebra (see Theorem 3) in one variable and by using this representation we obtain a general proof of a theorem of Strassman (see Corollary 1). In the case of many variables other results can be found in [2].
