DESCRIPTION: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 i
 ntegers replaced by rational numbers is still unknown\, and there is not e
 ven agreement among experts as to what the answer should be.\n\nTo join th
