    added a bit more text to the Idea-section at Wick rotation and in particular added cross-links with Osterwalder-Schrader theorem.

    added an overview-diagram to the Idea section (copied over from Euclidean field theory)

  1. Does this Wick rotation story ’lift’ to some relation between stable cohomotopy spaces?

    Right, so by the discussion at stable splitting of mapping spaces we have that the real cohomology of the space of spatially compactly supported cocycles in degree-4 cohomotopy on Minkowski spacetime (“Lorentzian instantons”) is equivalently correlators of Euclidean field theory on R 3×S 1R^3 \times S^1, hence Is Wick-rotated n-point functions of relativistic field theory on Minkowski spacetime at finite temperature.
