The new Lviv Scottish Book continues traditions of the famous "Scottish Book" (19351941) – a notebook with open mathematical problems inscribed by visitors of the famous Scottish Cafe. The original cafe was renovated in May 2014. Now, it is Restaurant “Szkocka” (Shevchenka Ave, 27, Lviv, Ukraine) and here you can find a copy of the Scottish Book and the new Lviv Scottish Book presented at the openin ceremony of the International Conference dedicated to the 120th anniversary of Kazimierz Kuratowski (27 September – 01 October 2016, Lviv, Ukraine).
As Stanisław Ulam wrote “the "Scottish Book" is an informal collection of problems in mathematics. It was begun in Lwow, in 1935. The story of the Scottish Book could also be called the "Tale of Two Coffee Houses", the Café Roma and, right next to it, the Café Szkocka, or Scottish Café. These two establishments are situated on a little square 100 or 200 yards from the University. …
The Scottish Café was situated at Akademichna street, 27 not far from the old University building.
The building ¹27 with two towers, resembling Scottish castle, was built in 1909 under a project of the architect Zbigniew Brochwicz Lewiński for Emil Weksler, an entrepreneur. In 19091944 the ground floor was occupied by the Scottish coffeehouse.
Stanisław Ulam wrote in his memories: “How did the book come about? One day Banach decided that because we talked about so very many things, we should write the ideas down whenever possible in order not to forget them. He bought a large and wellbound notebook in which we started to enter problems. The first one bears the date July 17, 1935. The Scottish book contains open problems posed by representatives of Lviv Mathematical School (S.Banach, S.Mazur, W.Orlicz, J.Schauder, H.Steinhaus, S.Ulam and others) of interwar period. The following mathematicians inscribed open problems to the Scottish Book: Alexandroff, Auerbach, Banach, Bogolubov, Borsuk, Eilenberg, Eidelheit, Fermant, Fréchet, Infeld, Kac, Kaczmarz, Kampe de Feriet, Knaster, Kuratowski, Łomnicki, Lusternik, Marcinkiewicz, Mazur, von Neumann, Nikliborc, Offord, Orlicz, Ruziewicz, Saks, Schauder, Schreier, Sierpiński, Sobolev, Steinhaus, Sternbach, Stoilow, Szpilrajn, Ulam, Wavre, Ward, Zygmunt. Usually, mathematicians writing problems to Lviv Scottish Book suggest some prize (a bottle of wine, a dinner in "Szkocka", etc.) for solutions."There is a charming story about one of the most famous of the problems in the Scottish Book which was posed by Mazur. This was problem number 153, which Mazur inserted into the Book on 6 November 1936. The problem asked (although not in these words) about the existence of Schauder bases in separable Banach spaces. As with many of the problems in the Scottish Book the proposer would offer a prize for their solution. Prizes offered included wine, spirits, or a meal in Cambridge but Mazur offered a live goose as the prize for this particular problem. Per Enflo showed in 1972 that the problem had a negative solution and, while in Warsaw lecturing on his solution, Mazur presented him with his prize, the live goose!" (S. Ulam) After World War II, Steinhaus at the University of Wrocław revived the tradition of the Scottish book by initiating The New Scottish Book, which is in the Library of Mathematics Faculty of Wrocław University.
The problems posed in the new Lviv Scottish Book can be found here on our site. Selected problems from the Book will be posted to Mathoverflow (on behalf of theuser Lviv Scottish Book). This site has convenient tools for tracing the problem progress.
