- Kazimierz Abramowicz was a Polish mathematician, working in the theory of analytic functions. In 1922 he defended his Ph.D. thesis "On hypergeometric functions with arbitrary amount of seemingly singular points" at the Warsaw University. He published over twenty scientific papers. His life and scientific achievements are described. Three photos of him are included. Paper finishes with a full list of his scientific papers, his talks and list of publications about him.

- Przedstawiono zawartość lwowskiego czasopisma Komunikaty Wydzialu Matematyczno-Fizycznego z lat 1940 i 1941, które znaleziono w archiwum. Wśród autorów byli: Stefan Banach, Leon Chwistek, Meier Eidelheit, Gertwagen, Jan Hercberg, Marian Mojżesz Jacob, Salomon Lubelski, Jan Mergentaler, Wasyl Miliańczuk, Marian Stanisław Puchalik, Antoni Wincenty Raabe, Stanisław Saks, Hugo Steinhaus, Zygmunt Zachorski, Miron Zarycki i Eustachy Żyliński. Do tej pory myśleliśmy, że zaginęły prace, ale na szczęście w archiwum znaleziono siedem rękopisów. Prezentujemy tytuły znalezionych artykułów z informacją, co będzie dalej z rękopisami.Uwaga: W artykule na stronie 74 po [Z5] powinno być:[Z6] E. Żyliński, O gremowskiej transformacji macierzy prostokątnych, 30-62, natomiast numery [Z6] - [Z17]^* powinny być numerowane jako [Z7] - [Z18]^*.

- Stein and Taibleson gave a characterization for f ϵ Lp(ℝn) to be in the spaces Lip (α, Lp) and Zyg(α, Lp) in terms of their Poisson integrals. In this paper we extend their results to Lipschitz-Orlicz spaces Lip (α, Lm) and Zygmund-Orlicz spaces Zyg (φ, Lm) and to the general function φ ϵ P instead of the power function φ(t)= tα. Such results describe the behavior of the Laplace equation in terms of the smoothness property of differences of f in Orlicz spaces Lm (IRn). More general spaces δk(φ,X, q) are also considered.

- Behavior of weak measures of noncompactness under real interpolation is investigated. It is shown that "convexity type" theorems hold true for weak measures of noncompactness.

Distribution and Rearranement Estimates of the Maximal Functions and Interpolation

- There are given necessary and sufficient conditions on a measure dμ(x)=w(x)dx under which the key estimates for the distribution and rearrangement of the maximal function due to Riesz, Wiener, Herz and Stein are valid. As a consequence, we obtain the equivalence of the Riesz and Wiener inequalities which seems to be new even for the Lebesgue measure. Our main tools are estimates of the distribution of the averaging function f** and a modified version of the Calderón-Zygmund decomposition. Analogous methods allow us to obtain K-functional formulas in terms of the maximal function for couples of weighted $L_p$-spaces.
