On -Ricci symmetric Sasakian manifolds
U. C. De,A. Sarkar 장전수학회 2008 Proceedings of the Jangjeon mathematical society Vol.11 No.1
The object of the present paper is to study Ø-Ricci symmetric Sasakian manifolds and Ø-Ricci symmetric Sasakian manifolds of dimension three. An example of three-dimensional Ø-Ricci symmetric Sasakian manifold is also given.
On slowly changing function and multiple zeros of difference of two meromorphic functions
H. P. Waghamore,S. S. Bhoosnurmath 장전수학회 2008 Proceedings of the Jangjeon mathematical society Vol.11 No.2
In this paper we compare the number of multiple zeros of f(z) − g(z) with the function rpK(r) where K(r) is a n- slowly changing function- satisfying K(cr) ∼ K(r) as r → ∞ for every fixed positive c.
Induced topology by proximal relations
F. A. Z. Shirazi,M. Sabbaghan 장전수학회 2008 Advanced Studies in Contemporary Mathematics Vol.17 No.2
By considering induced topologies by proximal relations on a transformation semigroup we introduce a class of interesting topologies with nice properties; moreover when the phase space is a fort space (or some of its generalizations), these transformation semigroups turn simple enough such that their Ellis semigroups can be calculated completely.
Modelling thread synchronization in Java using generalized net
P. Tcheshmedjiev,E. Sotirova 장전수학회 2006 Proceedings of the Jangjeon mathematical society Vol.9 No.1
Modelling thread synchronization using generalized net is very important for both understanding thread synchronization and ensuring thread safety. The proposed model provides a mechanism for descibing the threads and their transitions to different states depending on object locks. This approach allows describing and simulating the whole synchronization process of a given multithreaded application.
Homotopy analysis and Homotopy Pade methods for mixed Volterra-Fredholm integral equations
S. Fazeli,H. Kheiri,G. Hojjati 장전수학회 2010 Advanced Studies in Contemporary Mathematics Vol.20 No.4
In this paper, approximate analytical solution of the mixed Volterra-Fredholm inte-gral equation is obtained by the Homotopy analysis and the Homotopy Pade methods. The obtained approximation by using Homotopy method contains an auxiliary parameter which is a simple way to control and adjust the convergence region and rate of solution series. The approximation solutions by [m,m] Homotopy Pade technique is often independent of auxiliary parameter h and this technique accelerates the convergence of the related series.
Parallelism in nested loops with unimodular transformation and affine partitioning
F. A. Torkey,A. A. Salah,N. M. El Desouky,S. A. Gomaa 장전수학회 2008 Advanced Studies in Contemporary Mathematics Vol.17 No.1
Executing a program in parallel needs not only to find sufficient parallelism in a program, but it is also important that we minimize the synchronization and communication overheads in the parallelized program. Many of loop transformations have been developed to extract the parallelism from nested loops. In this paper, two loop transformations are compared; the unimodular transformation and the affine partitioning. The study shows that unimodular transformation is better than affine partitioning when the nested loops have a one statement and the dependence exists at this statement. While affine partitioning is more effective when the nested loops have a sequence of statements and the dependence exists between these different statements.
F. A. Z. Shirazi 장전수학회 2007 Advanced Studies in Contemporary Mathematics Vol.14 No.2
The main aim of the folowing text is to classify topological spaces in the point of linear connectivity, i.e., in the toplological space X ifa,b ∈, X , then for nonzero cardinal numbers β α, β " (α ,β ) − linear connection degree of (a,b) ", which is a cardinal number, will be introduced.
A note on interval-valued inclusion measures
장이채,김현미,김태균 장전수학회 2009 Proceedings of the Jangjeon mathematical society Vol.12 No.2
In this paper, we will define interval-valued inclusion measures and consider hybrid monotonic inclusion measures and investigate some properties of them. Furthermore, we discuss some relations between interval-valued inclusion measures and hybrid monotonic inclusion implicators.
Examples of a q-umbral calculus
Thomas Ernst 장전수학회 2008 Advanced Studies in Contemporary Mathematics Vol.16 No.1
We ilustrate the use of the tilde operator and the general-ized enition for q-hypergeometric series to quadratic transformations, andtrigonometric functions.The second part deals with aplications to double basic series and q-Kamp´e de F´eriet functions, the xpansion technique of Burchnal-Chaundyis used. An extension formula in the spirit of Chaundy is proved.
