We introduce an invariant of a hyperbolic knot, which is a map α ↦ α() from ℚ/ℤ to matrices with entries in ℚ¯[[]] and with rows and columns indexed by the boundary parabolic SL2(ℂ) representations of the fundamental group of the knot. These matrix invariants have a rich structure: (a) their (σ₀, σ₁...
