ABSTRACT
The author mainly uses the Galerkin approximation method and the iteration inequalities of the L-Maslov type index theory to study the properties of brake subharmonic solutions for the Hamiltonian systems ż( t) = J∇H( t, z( t)), where $$H(t,z) = \tfrac{1} {2}(\hat B(t)z,z) + \hat H(t,z),\hat B(t)$$, is a semipositive symmetric continuous matrix and Ĥ is unbounded and not uniformly coercive. It is proved that when the positive integers j and k satisfy the certain conditions, there exists a jT-periodic nonconstant brake solution zj such that zj and zkj are distinct.

    In this paper, we consider a preconditioned SAOR iterative method for solving linear system Ax = b. We prove its convergence and give more comparison results of the spectral radius for the case when A is an H-matrix or a strictly diagonally dominant matrix. Numerical example are also given to...

    Abstract We prove Strassen's law of the iterated logarithm for sums $${\sum^{N}_{k=1} f(n_kx),}$$ where f is a smooth periodic function on the real line and $${(n_k)_{k \geqq 1}}$$ is an increasing random sequence. Our results show that classical results of the theory of lacunary series remain...

    Using matrix iterations of ccc posets, we prove the consistency with ZFC of some cases where the cardinals on the right hand side of Cichon's diagram take two or three arbitrary values (two regular values, the third one with uncountable cofinality). Also, mixing this with the techniques in J...

    The quadratically convergent algorithms for training SVM with smoothing methods are discussed in this paper. By smoothing the objective function of an SVM formulation, Lee and Mangasarian [Comput. Optim. Appl. 20(1):5-22, 2001 ] presented one such algorithm called SSVM and proved that the error...

This combines the flexibility of the graph structure with higher efficiency due to higher data locality. The...

    We present a technique for the iterative diagonalization of random-phase approximation (RPA) matrices, which are encountered in the framework of time-dependent density-functional theory (TDDFT) and the Bethe-Salpeter equation. The non-Hermitian character of these matrices does not permit a...

    We studied the iterative algorithm in Tung et al. (2010) to find out that their assertion is questionable. We derived two new relations between safe factor and order quantity so that we can execute the iterative algorithm proposed by Wu and Ouyang (2001). We have proved that three generated...

    A new iterative procedure is formulated in this paper known as the interval midpoint symmetric single-step IMSS2-5D procedure. In this paper, we consider this new procedure in order to describe the rate of convergence of the IMSS2-5D procedure. It is analytically proven that the IMSS2-5D...
