A NOTE ON THE UNIQUENESS AND THE NON-DEGENERACY OF POSITIVE RADIAL SOLUTIONS FOR SEMILINEAR ELLIPTIC PROBLEMS AND ITS APPLICATION Shinji ADACHI, Masataka SHIBATA, Tatsuya WATANABE 数学物理学报(英文版). 2018 (4):  1121-1142.  DOI: 10.1016/S0252-9602(18)30803-8 摘要 ( 119 )   RICH HTML PDF   收藏 In this paper, we are concerned with the uniqueness and the non-degeneracy of positive radial solutions for a class of semilinear elliptic equations. Using detailed ODE analysis, we extend previous results to cases where nonlinear terms may have sublinear growth. As an application, we obtain the uniqueness and the non-degeneracy of ground states for modified Schrödinger equations. 参考文献 | 相关文章 | 计量指标

BURKHOLDER-GUNDY-DAVIS INEQUALITY IN MARTINGALE HARDY SPACES WITH VARIABLE EXPONENT 刘培德, 王茂发 数学物理学报(英文版). 2018 (4):  1151-1162.  DOI: 10.1016/S0252-9602(18)30805-1 摘要 ( 116 )   RICH HTML PDF   收藏 In this article, by extending classical Dellacherie's theorem on stochastic sequences to variable exponent spaces, we prove that the famous Burkholder-Gundy-Davis inequality holds for martingales in variable exponent Hardy spaces. We also obtain the variable exponent analogues of several martingale inequalities in classical theory, including convexity lemma, Chevalier's inequality and the equivalence of two kinds of martingale spaces with predictable control. Moreover, under the regular condition on σ-algebra sequence we prove the equivalence between five kinds of variable exponent martingale Hardy spaces. 参考文献 | 相关文章 | 计量指标

THE OSCILLATION OF THE POISSON SEMIGROUP ASSOCIATED TO PARABOLIC HERMITE OPERATOR 李平, 马聪变, 侯友良 数学物理学报(英文版). 2018 (4):  1214-1226.  DOI: 10.1016/S0252-9602(18)30809-9 摘要 ( 76 )   RICH HTML PDF   收藏 Let O(PτL) be the oscillation of the Possion semigroup associated with the parabolic Hermite operator L=∂t-△+|x|2. We show that O(PτL) is bounded from Lp(Rn+1) into itself for 1 < p < ∞, bounded from L1(Rn+1) into weak-L1(Rn+1) and bounded from Lc∞ (Rn+1) into BMO(Rn+1). In the case p=∞ we show that the range of the image of the operator O(PτL) is strictly smaller than the range of a general singular operator. 参考文献 | 相关文章 | 计量指标

A NOTE ON EXACT CONVERGENCE RATE IN THE LOCAL LIMIT THEOREM FOR A LATTICE BRANCHING RANDOM WALK 高志强 数学物理学报(英文版). 2018 (4):  1259-1268.  DOI: 10.1016/S0252-9602(18)30812-9 摘要 ( 71 )   RICH HTML PDF   收藏 Consider a branching random walk, where the underlying branching mechanism is governed by a Galton-Watson process and the moving law of particles by a discrete random variable on the integer lattice Z. Denote by Zn(z) the number of particles in the n-th generation in the model for each z ∈ Z. We derive the exact convergence rate in the local limit theorem for Zn(z) assuming a condition like "EN(log N)1+λ < ∞" for the offspring distribution and a finite moment condition on the motion law. This complements the known results for the strongly non-lattice branching random walk on the real line and for the simple symmetric branching random walk on the integer lattice. 参考文献 | 相关文章 | 计量指标

A CORRECTOR-PREDICTOR ARC SEARCH INTERIOR-POINT ALGORITHM FOR SYMMETRIC OPTIMIZATION M. PIRHAJI, M. ZANGIABADI, H. MANSOURI 数学物理学报(英文版). 2018 (4):  1269-1284.  DOI: 10.1016/S0252-9602(18)30813-0 摘要 ( 59 )   RICH HTML PDF   收藏 In this paper, a corrector-predictor interior-point algorithm is proposed for symmetric optimization. The algorithm approximates the central path by an ellipse, follows the ellipsoidal approximation of the central-path step by step and generates a sequence of iterates in a wide neighborhood of the central-path. Using the machinery of Euclidean Jordan algebra and the commutative class of search directions, the convergence analysis of the algorithm is shown and it is proved that the algorithm has the complexity bound O(√rL) for the well-known Nesterov-Todd search direction and O(rL) for the xs and sx search directions. 参考文献 | 相关文章 | 计量指标

DEVIATION OF THE ERROR ESTIMATION FOR VOLTERRA INTEGRO-DIFFERENTIAL EQUATIONS Mohammad ZAREBNIA, Reza PARVAZ, Amir SABOOR BAGHERZADEH 数学物理学报(英文版). 2018 (4):  1322-1344.  DOI: 10.1016/S0252-9602(18)30817-8 摘要 ( 66 )   RICH HTML PDF   收藏 In this paper, we study an efficient asymptotically correction of a-posteriori error estimator for the numerical approximation of Volterra integro-differential equations by piecewise polynomial collocation method. The deviation of the error for Volterra integrodifferential equations by using the defect correction principle is defined. Also, it is shown that for m degree piecewise polynomial collocation method, our method provides O(hm+1) as the order of the deviation of the error. The theoretical behavior is tested on examples and it is shown that the numerical results confirm the theoretical part. 参考文献 | 相关文章 | 计量指标
