A few words about history of extremal problems at Moscow University
We present here some evidence of the activity of Banach Lwów School of functional analysis in the field of topological algebras. We shall list several results connected with such names as Stanisław Mazur (1905-1981), Maks (Meier) Eidelheit (1910-1943), Stefan Banach (1892-1945) and Andrzej Turowicz (1904-1989) showing that if the war had not interrupted this activity we could expect more interesting results in this direction.
Questo lavoro esamina i contributi scientifici portati dalla scuola italiana di Analisi matematica nella prima metà del 20° secolo.
