چکیده
Let a(z) be a meromorphic function having in the disk |z| < R precisely λ poles. In this work for the (λ−1)th row of the Padé table of a(z) the set of uniform convergence is explicitly obtained. The present note is a supplement to the previous work of the author (J. Approx. Theory, 123(2003), 160-207). In the theory of uniform convergence of the Padé approximants the principal question is if the presence of limit points of poles for a sequence of the Padé approximants in the disk D is the unique obstraction for the unuform convergence of the sequence on compact subsets of D. For the diagonal sequence the affirmative answer has been given (under some normality conditions) by A.A. Gončar [1]. In the paper [2] it was found all limit points of poles of the Padé approximants for the row known as the last intermediate row of the Padé table for a meromorphic function. In the present note we are going to show that limit points of poles for this row are also the unique obstraction for the uniform convergence. Thus taking into account the results of [2] we can obtain the set of uniform convergence for the last intermediate row. Recall relevant definitions and statements. Let a(z) be a function which is meromorphic in the diskDR = {

J an 2 00 5 Not all limit points of poles of the Padé approximants are obstructions for uniform convergence
In the work it is shown that not all limit points of poles of the Padé approximants for the last intermediate row are obstructions for uniform convergence of the whole row to an approximable function. The corresponding examples are constructed. For some classes of meromorphic functions it is found under what conditions the limit point is not the obstruction for the uniform convergence of the la...
متن کاملAlmost Sure Convergence Rates for the Estimation of a Covariance Operator for Negatively Associated Samples
Let {Xn, n >= 1} be a strictly stationary sequence of negatively associated random variables, with common continuous and bounded distribution function F. In this paper, we consider the estimation of the two-dimensional distribution function of (X1,Xk+1) based on histogram type estimators as well as the estimation of the covariance function of the limit empirical process induced by the se...
متن کاملA COMMON FRAMEWORK FOR LATTICE-VALUED, PROBABILISTIC AND APPROACH UNIFORM (CONVERGENCE) SPACES
We develop a general framework for various lattice-valued, probabilistic and approach uniform convergence spaces. To this end, we use the concept of $s$-stratified $LM$-filter, where $L$ and $M$ are suitable frames. A stratified $LMN$-uniform convergence tower is then a family of structures indexed by a quantale $N$. For different choices of $L,M$ and $N$ we obtain the lattice-valued, probabili...

Suppose $textbf{M}_{n}$ is the vector space of all $n$-by-$n$ real matrices, and let $mathbb{R}^{n}$ be the set of all $n$-by-$1$ real vectors. A matrix $Rin textbf{M}_{n}$ is said to be $textit{row substochastic}$ if it has nonnegative entries and each row sum is at most $1$. For $x$, $y in mathbb{R}^{n}$, it is said that $x$ is $textit{sut-majorized}$ by $y$ (denoted by $ xprec_{sut} y$) if t...

In this paper, the nonlinear differential equation for the convection of the temperature distribution of a straight fin with the thermal conductivity depends on the temperature is solved using Adomian Decomposition Method and Padé approximation(PADM) for boundary problems. Actual results are then compared with results obtained previously using digital solution by Runge–Kuttamethod and a diffe...
