Both of his parents were survivors of concentration camps and taught him "The only things you own are in your heart and brain". So he became a mathematician. Frankl often lectures about racial discrimination.[7]
Adolescence and abilities
He could multiply two digit numbers when he was four years old.[8] Frankl speaks 12 languages (Hungarian, English, Russian, Swedish, French, Spanish, Polish, German, Japanese, Chinese, Thai, Korean) and lectured mathematics in many countries in these languages. He has travelled to more than 100 countries.[9][10]
Activities
Frankl learnt juggling from Ronald Graham. He and Vojtěch Rödl solved a $1000 problem of Paul Erdős. Zsolt Baranyai helped Frankl to get a scholarship in France, where he became a CNRS research fellow.[citation needed]
For 1984 to 1990, Frankl and Akiyama worked hard organizing a Japanese mathematical Olympiad team, and as a consequence the Japanese team is now a regular participant of the International Mathematical Olympiad.[11][12]
He authored more than thirty books in Japanese, and with László Babai, he wrote the manuscript of a book on "Linear Algebra Methods in Combinatorics".[citation needed] With Norihide Tokushige he is the coauthor of the book Extremal Problems For Finite Sets (American Mathematical Society, 2018).[14]
For any finite union-closed family of finite sets, other than the family consisting only of the empty set, there exists an element that belongs to at least half of the sets in the family.
