R_m边割存在的充分条件
(20020325)Rm 边割是这样一种边割 ,它将连通图分割为各分支的阶都不小于m的不连通图 .设G是一个阶不小于 2m的连通图 .用c(G)表示G的周长 (即G中最长圈的长度 ) ,如果c(G)≥m +1,那么G含有Rm 边割 ,而且周长c的下界在一定程度上是不可改进的

Rainbow Hfactors of complete suniform rpartite hypergraphs
(20080714)We say a suniform rpartite hypergraph is complete, if it has a vertex partition {V1, V2, ..., Vr} of r classes and its hyperedge set consists of all the ssubsets of its vertex set which have at most one vertex in ... 
Ramsey numbers, graph eigenvalues, and a conjecture of Cao and Yuan
(Elsevier Inc., 2014 Octob)Let N be a positive integer and R(N,N) denote the Ramsey number (see [15] or [11]) such that any graph with at least R(N,N) vertices contains a clique with N vertices or an independent set with N vertices. We show that any ... 
Random duality
(SCI CHINA SER A, 200910)The purpose of this paper is to provide a random duality theory for the further development of the theory of random conjugate spaces for random normed modules. First, the complicated stratification structure of a module ... 
RAPID SIMULTANEOUS ANALYSIS OF 1NAPHTHOL AND 2NAPHTHOL IN WATER SAMPLES BY DERIVATIVE VARIABLEOFFSET SYNCHRONOUS FLUORESCENCE SPECTROSCOPY
(199405)Derivative variableoffset synchronous fluorescence spectroscopy is developed to improve the spectral resolution and the selectivity of fluorescence measurements. 1naphthol and 2naphthol are employed to evaluate the ... 
Rate of approximation for the Bezier variant of Balazs Kantorovich operators
(200708)In the present paper we study the Bezier variant of the well known BalazsKantorovich operators L(n,alpha)(f, x), alpha >= 1. We establish the rate of convergence for functions of bounded variation. For particular value ... 
Rate of Convergence of a New Type Kantorovich Variant of BleimannButzerHahn Operators
(Hindawi Publishing Corporation, 2009)A new type Kantorovich variant of BleimannButzerHahn operator J(n) is introduced. Furthermore, the approximation properties of the operators J(n) are studied. An estimate on the rate of convergence of the operators J(n) ... 
Rate of convergence of BaskakovBezier type operators for locally bounded functions
(2002NOVD)In this paper, we introduce BaskakovBezier operator Bn,Balpha which is an operator of probabilistic type. We study the rate of convergence of the operator Bn,Balpha for locally bounded functions by using some inequalities ... 
Rate of pointwise approximation for locally bounded functions by Szasz operators
(20050715)In this paper the asymptotic behavior of Szasz operators for locally bounded functions f is studied at points x where f (x +) and f (x ) exist. An asymptotic estimate of this type approximation is obtained by using some ... 
Rates of approximation of bounded variation functions by two generalized MeyerKonig and Zeller type operators
(200005)In this paper, the approximation behaviours of two generalized MeyerKonig and Zeller type operators Mn,Malpha(f, x) and (M) over cap(n,alpha)(f, x) are studied. By means of the decomposition technique of functions of ... 
Real Fast StructurePreserving Algorithm for Eigenproblem of Complex Hermitian Matrices
(HINDAWI PUBLISHING CORPORATION, 2013)It is well known that the flops for complex operations are usually 4 times of real cases. In the paper, using real operations instead of complex, a real fast structurepreserving algorithm for eigenproblem of complex ... 
REALVARIABLE CHARACTERIZATIONS OF HARDY SPACES ASSOCIATED WITH BESSEL OPERATORS
(ANAL APPL, 201107)Let lambda > 0, p is an element of ((2 lambda + 1)/(2 lambda + 2), 1], and Delta(lambda) = d(2)/dx(2)  2 lambda/x d/dx be the Bessel operator. In this paper, the authors establish the characterizations of atomic Hardy ... 
Recollements of extension algebras
(SCIENCE IN CHINA, 200307)Let A be a finitedimensional algebra over arbitrary base field k. We prove: if the unbounded derived module category D− (ModA) admits symmetric recollement relative to unbounded derived module categories of two ... 
Recollements, idempotent completions and tstructures of triangulated categories
(J ALGEBRA, 20080401)We first prove that the idempotent completion of a right or left recollement of triangulated categories is still a right or left recollement, then show that the tstructure on a triangulated category is compatible with ... 
Recollement导出的共变与反变有限子范畴
(2011)证明了若3个三角范畴允许有1个rECOllEMEnT,则rECOllEMEnT两端三角范畴上的共变有限子范畴可以诱导出中间三角范畴上的1个共变有限子范畴;对偶地,rECOllEMEnT两端三角范畴上的反变有限子范畴也可诱导出中间三角范畴上的1个反变有限子范畴.进一步地,将其应用到具体范畴,得到几类导出范畴的共变有限子范畴及反变有限子范畴. 
Recursive formulae for enumeration of LMconjugated circuits in structurally related benzenoid hydrocarbons
(200110)The linearly independent and minimal conjugated (LMconjugated) circuits of benzenoid hydrocarbons play the central role in the conjugated circuit model. For a general case, the enumeration of LMconjugated circuits may ... 
REDUCIBLE CHAINS IN SEVERAL TYPES OF 2CONNECTED GRAPHS
(1992)Let G0, G1, G2 and G3 denote the sets of all 2connected graphs, minimally 2connected graphs, critically 2connected graphs, and critically and minimally 2connected graphs, respectively. We introduce the concept of ... 
Reducible chains of planar 1cycle resonant graphs
(20040128)A connected graph G is said to be kcycle resonant if, for 1 less than or equal to t less than or equal to k, any t disjoint cycles in G are mutually resonant, that is, there is a perfect matching M of G such that each of ...
