Asymptotic equivalence of length complexity and Turing step count in thickened Turing-machine bordisms
Prove that for the dynamical bordism M_G obtained by thickening a given Turing machine graph G and equipped with the flat tube metric g_0, the length complexity LenC_{(M_G,g_0)}(n) of computing on input n is asymptotically equal to the number of Turing steps T(n), i.e., establish that lim_{n→∞} LenC_{(M_G,g_0)}(n) / T(n) = 1.

We conjecture that the length with respect to this metric is actually asymptotically comparable to the usual time complexity of the function it computes.
