O’Neill’s theorem for PL approximations

Journal of Fixed Point Theory and Applications
AbstractWe present a version of O’Neill’s theorem (Theorem 5.2 in O’Neill in Am J Math 75(3):497–509, 1953) for piecewise linear approximations.

The inverse theorem of approximation theory in Smirnov-Orlicz classes

, 2012
Let F be a Dini- smooth curve in the complex plane C. In this study we prove inverse theorem of approximation theory by polynomials in Smirnov-Orlicz classes EM (G)

The approximation of bivariate functions by bivariate operators and GBS operators

Journal of Numerical Analysis and Approximation Theory, 2011
In this paper we demonstrate a general approximation theorem for the bivariate functions by bivariate operators and GBS (Generalized Boolean Sum) operators.

Arithmetic Demailly approximation theorem

Advances in Mathematics
We generalize the Demailly approximation theorem from complex geometry to Arakelov geometry.As an application, let $X/\mathbb{Q}$ be an integral projective variety and $\overline N$ be an adelic line bundle on $X$, we prove that $\operatorname{ess}(\overline N) \geq 0$ $\Longrightarrow $ $\overline N$ pseudo-effective.

Best Simultaneous Approximation of Functions and a Generalized Minimax Theorem [PDF]

Best simultaneous approximation (BSA) for finitely or infinitely many functions are considered under the uniform norm and other important norms. Characterization theorems for a BSA from a finite-dimensional subspace are obtained by a generalized minimax ...

Approximate Selection Theorems and Their Applications

Journal of Mathematical Analysis and Applications, 1997
Let \(X\) be a paracompact space, \(Y\) a locally convex linear topological space, and \(F:X\to Y\) a multifunction with convex values. \(F\) is called sub-lsc if for each \(x\in X\) and each neighbourhood of zero in \(Y\) there is a \(z\in F(x)\) and a neighbourhood \(U(x)\) of \(x\) in \(X\) such that for each \(y\in U(x)\), \(z\in F(y)+V\).

A covering approach to eigenvalue bounds for the fractional p-Laplacian

Demonstratio Mathematica
We study Weyl-type lower bounds for the variational eigenvalues associated with a weighted fractional p-Laplacian on bounded domains with Lipschitz boundary in a critical (limit) case.

A Generalisation of Steenrod's Approximation Theorem

, 2006
In this paper we aim for a generalisation of the Steenrod Approximation Theorem from, concerning a smoothing procedure for sections in smooth locally trivial bundles. The generalisation is that we consider locally trivial smooth bundles with a possibly infinite-dimensional typical fibre.
