The Hilbert’s-Tenth-Problem Operator

For a ring R, Hilbert’s Tenth Problem HTP (R) is the set of polynomial equations over R, in several variables, with solutions in R. We view HTP as an operator, mapping each set W of prime numbers to HTP (Z[W−1]), which is naturally viewed as a set of polynomials in Z[X1, X2, . . .]. For W = ∅, it is a famous result of Matiyasevich, Davis, Putnam, and Robinson that the jump ∅′ is Turing-equivale...

With a wide variety in behavior and form, the robots in the exhibition created a sense of the broad range of function in the robotic community. As one of the only events with no scoring or judges, the exhibition takes on a very different fe...
