Hilbert's tenth problem asked for an algorithm that, given a multivariable polynomial equation with integer coefficients, would decide whether there exists a solution in integers. Around 1970, Matiyasevich, building on earlier work of Davis, Putnam, and Robinson, showed that no such algorithm exists. But the answer to the analogous question with integers replaced by rational numbers is still unknown, and there is not even agreement among experts as to what the answer should be.

Address: 55 Lexington Avenue (between 24th street and 25th street). Room 14-270 on the 14th floor.

Drinks and pastries will be served. The talk itself would start at 12:20pm.

Interested participants are welcome to join us for lunch with the speaker after the talk.
