This paper presents a coherence theorem for star-autonomous categories exactly analogous to Kelly’s and Mac Lane’s coherence theorem for symmetric monoidal closed categories. The proof of this theorem is based on a categorial cut-elimination result, which is presented in some detail. Mathematics Subject Classification (2000): 03F05, 03F52, 18D10, 18D15, 19D23

We construct explicit solutions of the Hermitian Yang-Mills equations on the noncommutative space C θ . In the commutative limit they coincide with the standard instantons on CP written in local coordinates.
