<正>Vitali Type Convergence Theorems for Banach Space Valued Integrals Marek BALCERZAK Kazimierz MUSIAL Abstract Let(Ω,∑,μ)be a complete probability space and let X be a Banach space.We introduce the notion of scalar equi-convergence in measure which being applied to sequences of Pettis integrable functions generates a new convergence theorem.We also obtain a Vitali type I-convergence theorem for Pettis integrals where I is an ideal on N.On Universally Left-stability ofε-Isometry  相似文献

<正>Rough Marcinkiewicz Integrals with Mixed Homogeneity on Product Spaces Feng LIU Huo Xiong WU Abstract In this paper,the parabolic Marcinkiewicz integral operators on the product spaces Rm×Rm×Rn(m,n≥2)are studied.The Ln(m,n≥2)are studied.The Lp-boundedness for such operators are established under rather weak size conditions of the kernels,which essentially improve or extend certain previous results.  相似文献

<正>L(j,k)-number of Direct Product of Path and Cycle Wai Chee SHIU Qiong WU Abstract For positive numbers j and k,an L(j,k)-labeling f of G is an assignment of numbers to vertices of G such that |f(u)-f(v)|≥j if uv∈E(G),and |f(u)-f(v)|≥k if d(u,v)=2.Then the span of f is the difference between the maximum and the minimum numbers assigned by f.The L(j,k)-number of G,denoted byλ_(j,k)(G),is the minimum span over  相似文献

<正>A New Class of Generalized Close-to-Starlike Functions Defined by the Srivastava-Attiya Operator H.M.SRIVASTAVA Dorina RADUCANU Grigore S.SALAGEAN Abstract In this paper,we consider a new class CS_(s,b)* of generalized close-to-starlike functions, which is defined by means of the Srivastava-Attiya operator J_(s,b) involving the Hurwitz-Lerch Zeta functionΦ(z,s,a).Basic results such as inclusion relations,coefficient inequalities and other interesting properties of this class are investigated.Relevant connections of some of  相似文献

<正>Total Restrained Bondage in Graphs Nader JAFARI RAD Roslan HASNI Joanna RACZEK Lutz VOLKMANN Abstract A subset S of vertices of a graph G with no isolated vertex is a total restrained dominating set if every vertex is adjacent to a vertex in S and every vertex in V(G)-S is also adjacent to a vertex in V(G)-S.The total restrained domination number of G is the minimum cardinality of a total restrained dominating set of G.In this paper we initiate the study of  相似文献

<正>The Discrete Subgroups and Jφrgensen's Inequality for SL(m,C_p) Wei Yuan QIUJing Hua YANGYong Cheng YIN Abstract In this paper,we give discreteness criteria of subgroups of the special linear group on Q_p or C_p in two and higher dimensions.Jφrgensen's inequality gives a necessary condition for a non-elementary group of Mbius transformations to be discrete.We give a version  相似文献

<正>Regularity of the Inverse of a Homeomorphism with Finite Inner Distortion Chang Yu GUO Abstract Let f:Ω→f(Ω)R~n be a W~(1,1)-homeomorphism with L~1-integrable inner distortion.We show that finiteness of min{lip_f(x),k_f(x)},for every x∈Ω\E,implies that f~(-1)∈W~(1,n)and has finite distortion,provided that the exceptional set E hasσ-finite H~1-measure.Moreover,f has finite distortion,differentiable a.e.and the Jacobian J_f0 a.e.  相似文献

<正>Distances between Elements of a Semigroup and Estimates for Derivatives Zohra BENDOUAD Isabelle CHALENDAR Jean ESTERLE Jonathan R.PARTINGTON Abstract This paper is concerned first with the behaviour of differences T(t) - T(s) near the origin,where(T(t)) is a semigroup of operators on a Banach space,defined either on the positive real line or a sector in the right half-plane(in which case it is assumed analytic).For the non-quasinilpotent case extensions of results in the published literature are provided,with best possible constants;in the case of quasinilpotent semigroups on the half-plane,it is shown  相似文献

<正>Abstract In the "lost notebook",Ramanujan recorded infinite product expansions for 1/r~(1/2)-((1-5~(1/2))/2)r~(1/2) and 1/r~(1/2)-((1+5~(1/2))/2)r~(1/2), where r = r(q) is the Rogers-Ramanujan continued fraction.We shall give analogues of these results that involve Ramanujan's function k = k(q) = r(q)r~2(q~2).  相似文献

Asymptotic and Partial Asymptotic Hankel Operators on H^2(D^n)Anuradha GUPTA Bhawna GUPTA Abstract In this paper,we generalize the concept of asymptotic Hankel operators on H^2(D)to the Hardy space H^2(D^n)(over polydisk)in terms of asymptotic Hankel and partial asymptotic Hankel operators and investigate some properties in case of its weak and strong convergence.  相似文献

<正>Empirical Likelihood of Quantile Difference with Missing Response When High-dimensional Covariates Are Present Cui Juan KONG Han Ying LIANG Abstract We,in this paper,investigate two-sample quantile difference by empirical likelihood method when the responses with high-dimensional covariates of the two populations are missing at random.In particular,based on sufficient dimension reduction technique,we construct three empirical log-likelihood ratios for the quantile difference between two samples by using inverse probability weighting imputation,regression imputation as well as augmented inverse probability weighting imputation,respectively,and prove their asymptotic distributions.  相似文献
