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] His research is in combinatorics, especially in extremal combinatorics. He is the author of the union-closed sets conjecture.[7]

Personality

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.[8]

Adolescence and abilities

He could calculate multiplication of two digits[clarification needed] when he was four years old.[9] Frankl speaks 12 languages (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.[10][11]

Activities

When Frankl was a university student, he met Ronald Graham at IMC and learned juggling from him.[12] Frankl is friendly with Paul Erdős.[13][page needed] Imre Bárány helped Frankl to go to France to study mathematics.[14]

In 1984, Frankl learned five-ball juggling from Paul Klimek of the University of California, Santa Cruz.[15]

For 1984 to 1990, Frankl and some mathematician[who?] organized a Japanese mathematical Olympic team.[16] 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".[17] These hardest math puzzles produced two gold medalists at the International Mathematical Olympiad.[18][19]

Since 1998, he has been an external member of the Hungarian Academy of Sciences.[20]

Frankl conjecture

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}
