A Fix-Finite Approximation Theorem
Let \(E\) be a metrizable locally convex vector space whose topology is defined by a translation invariant metric \(d\) given by \(d(x,y)=\sum^\infty_{h=1}\frac1{2^n}\;\frac{p_n(x-y)}{1+p_n(x-y)}\).Let \(C(E)\) be the set of non-empty compact subsets of \(E\). For \(A,B\in C(E)\), the Hausdorff distance is defined as \(d_H(A,B)=\max\{P(A,B),P(B,A)\}\),

O’Neill’s theorem for PL approximations
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.

On the Jackson type inequality in the dyadic BMO space
In this paper the direct theorem of the approximation theory for functions from the dyadic Besov space is proved. Together with the inverse theorem, it allows to solve an interpolation problem between dyadic BMO and the dyadic Besov space.
