Challenge statement

Can the existence of integer solutions to a two-variable Diophantine equation be decided within a uniform exponential-time bound, or otherwise constrained by a natural size/height measure?

Why this challenge is in the ledger

Tests arithmetic geometry, decidability, height, finite-window reasoning, and the interface between symbolic equations and computational tractability.

τ-facing burden

Show whether τ gives a notion of address window, height, or finite obstruction that yields nontrivial constraints on Diophantine solution search.

First reviewer questions

  1. Is the τ notion of addressability comparable to standard height or bit-size measures?
  2. Does τ produce an algorithmic bound, a structural obstruction, or only an internal analogy?
  3. How does this interact with Hilbert's tenth problem and known decidability boundaries?
