Abstract: Abstract. Myasnikov, Ushakov, and Won introduced power circuits in 2012 to construct a polynomial-time algorithm for the word problem in the Baumslag group, which has a non-elementary Dehn function. Power circuits are computational structures that support addition and the operation (x,y) → x · 2y on integers. They also posed the question of decidability of the Diophantine problem over the structure ⟨N>0;+,x · 2y,≤,1⟩, which is closely related to power circuits. In this paper, we prove that the Diophantine problem over this structure is undecidable.
