Author(s): S.K. Bhambri et al.
Abstract: In this paper, we introduce the concepts of prime and weakly prime left ideals in ternary semiring and give some characterizations related to the same. The notion of weak msystem in ternary semiring is introduced and give some characterizations in terms of prime and weakly prime left ideals in ternary semirings. We also introduce the notion of weakly regular ternary semiring and prove some important results analogous to ring theory.
Keywords: Ternary semiring; Weakly prime left ideals; Weakly regular ternary semirings.

Title: A Short Note on Thirions Demons Algorithm
Vol.37(6) (2013) page: 813
Author(s): V. Bieta and T. Möller
Abstract: Thirions Demons algorithm, first introduced in [5], is an intuitive and widely used matching algorithm. In contrast to other algorithms it is not obvious, that there is any reasonable energy which is minimized by the Demons algorithm. In [6] it is shown, that Thirions Demons algorithm minimizes the energy introduced in [3] (cf. (1)). In order to show this result the authors used Lie theory. In this note a simplified proof is given using standard calculus on vector spaces instead of Lie theory.

Title: Syntactic Nearrings Associated With Group Semiautomata
Vol.37(6) (2013) page: 837
Author(s): Y. Fong et al.
Abstract: This is a brief survey in the structure theory of syntactic nearrings associated with group semiautomata which was initiated by M. Holcombe [17] since 1983. The basic idea was using the technique of automata theory, one can obtain a lot of interesting mathematics, saying syntactic nearrings, as well as applications. In this article, we present a series of interesting results of syntactic nearrings associated with group semiautomata and also some recent work on syntactic nearrings of odd dihedrial group that will be appeared in the near future.
Keywords: Syntactic nearring; Group semiautomaton.

Vol.37(6) (2013) page: 845
Author(s): A. Gholami and M. R. Mollaei
Abstract: In 2009 M.T arnauceanu introduced the concept of subgroup commutativity degree of a finite group G. This concept is arising interest in several areas of group theory in the last years. In this paper we try to study some inequalities of this notion such that these are open problem or type of subgroup commutativity degree of finite groups(see also [16, 21]).

Title: Characterization of the Group Dp(5) by Order Components, Where p ?? 5 is a Prime Number
Vol.37(6) (2013) page: 867
Author(s): M. Khademi and M.R. Darafsheh
Abstract: In this paper we prove that the group D_{p}(5) where p ≥ 5 is a prime number can be uniquely determined by its order components. The content of our paper is independent of a paper by H.G. Shi and G.Y. Chen and Z.J. Han published in the Southeast Asian Bull. Math. in 2011 that if G is a finite group and OC(G) denotes the set of order components of G,then OC(G)=OC(D_{p}(5)) if and only if G ≅ D_{p}(5). A main consequence of our result is the validity of the well known Thompson's conjecture for the group D_{p}(5), where p ≥ 5 is a prime number.

Title: Global Classical Solution to a Hyperbolic System of Conservation Laws in Oil Recovery
Vol.37(6) (2013) page: 887
Author(s): Y.C. Pang et al.
Abstract: The Cauchy problem for a hyperbolic system of conservation laws in oil recovery with continuous and piecewise smooth initial data is investigated. By local existence and uniqueness results and uniform a priori estimate for the C^{1} norm of smooth solutions, it is proven that, under some reasonable hypotheses on the initial data, the Cauchy problem admits a unique global continuous and piecewise smooth solution on t ≥ 0.

Author(s): I. Ramabhadra Sarma et al.
Abstract: The aim of this paper is to (a) generalize the known costruction method of a near ring (R^{n}, +,.) given by K.D. Magill, Jr to infinite dimensional in 1995, (b) Suggest new ways to define semilinear maps on a real linear space (X,+,·) and utilize these mappings λ to define near ring or near algebra sturctures X_{λ} on X, and (c) Prove a Hurwitz Frobenius type result to the effect that a nontrivial X_{λ} is a onedimensional algebra if all its nonzero elements are right invertible.

Title: On Monotonic Sequential Operators
Vol.37(6) (2013) page: 903
Author(s): M. Singha and S. De Sarkar
Abstract: Notions of monotonic sequential operators and their components (on and off) are introduced and sequential as well as generalized sequential topologies induced by them are studied. Some properties of such operators and their components have been derived using the concept of operators introduced by Á. Császá r and investigated the relations among themselves. The concept of connectors are also generalized. Expansion or contraction of a component of sequential set depends upon some other components of that sequential set; this kind of dependence plays the main role and yields plenty of results in this paper.

Title: Nonlinearity of Quartic Rotation Symmetric Boolean Functions
Vol.37(6) (2013) page: 951
Author(s): L. Yang et al.
Abstract: Nonlinearity of rotation symmetric Boolean functions is an important topic on cryptography algorithm. Let e ≥ 1 be any given integer. In this paper, we investigate the following question: Is the nonlinearity of the quartic rotation symmetric Boolean function generated by the monomial x_{0}x_{e}x_{2e}x_{3e} equal to its weight? We introduce some new simple subfunctions and develop new technique to get several recursive formulas. Then we use these recursive formulas to show that the nonlinearity of the quartic rotation symmetric Boolean function generated by the monomial x_{0}x_{e}x_{2e}x_{3e} is the same as its weight. So we answer the above question affirmatively. Finally, we conjecture that if l ≥ 4 is an integer, then the nonlinearity of the rotation symmetric Boolean function generated by the monomial x_{0}x_{e}x_{2e}...x_{le} equals its weight.
Keywords: Rotation symmetric Boolean function; Nonlinearity; Weight; Fourier transform.
