For any Legendrian knot 𝛫 in standard contact ℝ³, we relate counts of ungraded (1-graded) representations of the Legendrian contact homology DG-algebra (A(𝛫), ∂) with the n-colored Kauffman polynomial. To do this, we introduce an ungraded n-colored ruling polynomial, R¹ₙ, 𝛫(q), as a linear combinati...
