History and current state of recreational mathematics and its relation to serious mathematics
Bártlová, Tereza ; Pick, Luboš (advisor)
Dissertation abstract The present thesis is devoted to the study of recreational mathematics, with a particular emphasis on its history, its relation to serious mathematics and its educational benefits. The thesis consists of five papers. In the first one we investigate the history of recreational mathematics. We focus on the development of mathematical problems throughout history, and we try to point out the people who had an important influence on the progress of recreational mathematics. The second article is dedicated to Edwin Abbott Abbott and his book called Flatland. It is one of the first popularizing books on geometry. In the third article we review one of the prominent personalities of recreational mathematics, Martin Gardner. The fourth article is in some sense a sequel to the third one. It deals with treachery of mathematical intuition and mathematical April Fool's hoaxes. The last article is devoted to the implementation recreational mathematics to education of students. 1
Supremum operators and optimal Sobolev inequalities
Pick, Luboš
We study the problem of optimality of rearrangement-invariant norms for which a Sobolev-type inequality holds. A key role is played by a Hardy-type operator involving supremum.
