Convergence of Functions

2015
Major convergence concepts for sequences of real-valued functions will be considered in this chapter. We have already met four convergence concepts so far (viz., pointwise, uniform, almost everywhere, and convergence in L p ). These are reviewed and compared in this section.

Convergent Extensions of Grid‐Functions

Mathematische Nachrichten, 1988
AbstractIt is well‐known that functions u ϵ Wm,p (Ω) can be extended by a bounded linear operator E to functions Eu ≦ Wm,p(Rn), if Ω is CM‐regular and m ≦ M. Here we prove a corresponding result for grid‐functions with extension operators Eh converging to E and mention some applications.

Weak Convergence of a Certain Functional

Theory of Probability & Its Applications, 2002
Summary: We consider the functional \(T_n=(S_1^2+\cdots+S_n^2)/(nV_n^2)\) derived from a sequence \(\{X_n\}_{n\geq 1}\) of independent identically distributed random variables, where \(S_k=X_1+\cdots+X_k\), \(V_n^2=X_1^2+\cdots+X_n^2\). Let \(G\) be the distribution function of the random variable \(\int_{0}^{1}W^2(t) dt\), where \(W(t)\), \(t\in [0,1]\

CONVERGENCE OF CERTAIN FUNCTIONAL SERIES

Mathematics of the USSR-Izvestiya, 1967
Using the idea of extension of the system of functions {fk(x)} to an orthogonal one, the author establishes some assertions relating to convergence, (C,1)-summability and unconditional convergence almost everywhere of series in the system {fk(x)}.

Completely Convex Functions and Convergence

SIAM Journal on Mathematical Analysis, 1979
A function $f(x)$ is completely convex (c.c.) on $[0,1]$ if $( - 1)^k f^{(2k)} (x) \geqq 0$ for $k \geqq 0$ and all x in $[0,1]$. This paper studies the convergence of the partial sums of the Maclaurin series of the function; in particular, how quickly the partial sums turn into a c.c. function. It is shown that no matter where the series is truncated,

On the Convergence of Sequences of Rational Functions

SIAM Journal on Numerical Analysis, 1967
There are numerous kinds of sequences of rational functions, such as sequences of Pad6 approximants and sequences of rational functions of best approximation on a given point set, where the poles of the individual functions are not known even asymptotically, and no effective methods for their determination are at hand.

On Uniform Convergence of Continuous Functions and Topological Convergence of Sets

Canadian Mathematical Bulletin, 1983
AbstractLet X and Y be metric spaces. This paper considers the relationship between uniform convergence in C(X, Y) and topological convergence of functions in C(X, Y), viewed as subsets of X×Y. In general, uniform convergence in C(X, Y) implies Hausdorff metric convergence which, in turn, implies topological convergence, but if X and Y are compact ...

More on Convergence of Continuous Functions and Topological Convergence of Sets

Canadian Mathematical Bulletin, 1985
AbstractLet C(X, Y) denote the set of continuous functions from a metric space X to a metric space Y. Viewing elements of C(X, Y) as closed subsets of X × Y, we say {fn} converges topologically to f if Li fn = Lsfn = f. If X is connected, then topological convergence in C(X,R) does not imply pointwise convergence, but if X is locally connected and Y is
