We prove that every continuous linear operator acting on a stable, nuclear power series space is a commutator, so in particular our theorem holds for the space of all entire functions, holomorphic functions on the unit disc or smooth functions. We also show that on the product of Fréchet spaces ∏i=1∞X\documentclass[12pt]{minimal} \usepackage{amsmat...

The most traditional approach to the problem of multiple hypotheses testing has been Bonferroni’s method but, in the last years, a lot of attention has been paid to Benjamini–Hochberg’s method. In this article, a general procedure is considered, where the prior information (when available) and the cost of erroneous decisions are incorporated in a s...

Recently, Samet and Vetro proved a fixed point theorem for mappings satisfying a general contractive condition of integral type in orbitally complete metric spaces (Samet and Vetro, Chaos Solitons Fractals 44:1075–1079, 2011). Our aim in this paper is to present a version of the results obtained in the above mentioned paper in the context of ordere...
