Péter Frankl (born 26 March 1953 in Kaposvár, Somogy County, Hungary) is a Hungarian mathematician, street performer, columnist and educator.[4] Frankl studied Mathematics in University Paris Diderot and has lived in Japan since 1988, where he sometimes appears on NHK. Though not as popular as he once was, he still performs juggling in public spaces around Tokyo. Frankl won a gold medal at the International Mathematical Olympiad in 1971. He has seven joint papers with Paul Erdős,[5] and eleven joint papers with Ronald Graham.[6]

Personality[edit]

Frankl was named Peter by his father to hide his Jewish background. His father told him, "Our Jewishness is on our heart and brain". So he became a mathematician. Frankl often speaks about racial discrimination.[7]

Activity[edit]

His research is in combinatorics, especially in extremal combinatorics. For example, he is the author of the famous open problem, the union-closed sets conjecture.[8]

He could calculate multiplication of two digits when he was four years old.[9] Frankl speaks 12 languages (English, Russian, Swedish, French, Spanish, Polish, German, Japanese, Chinese, Thai, Korean) and lectured mathematical education in many countries. He says that sometimes native people ignored him because of his non-native pronunciation.[clarification needed][10]

In 1984 Peter Frankl learned 5 balls juggling (7,4,4 pattern) from Paul Klimek of the University of California, Santa Cruz. [11]

Since 1998, he has been an external member of the Hungarian Academy of Sciences.[12]

He created mathematical unique puzzle problems concerned about Thue–Siegel–Roth theorem, puzzle of Kontsevich, graph theory, combinatorics for students in the mathematical journal "大学への数学".[13] These hardest math puzzles gave birth to two gold medalists in IMO.[14][15]

Frankl Conjecture[edit]

Let F be a k-uniform family of subsets of a set of n elements. Let t ≥ 2 and suppose that for any pair A, B of distinct members of F, it is not the case that |A ∩ B|≡k (mod t) . Then

|F| \leq \binom n{t-1}
