Last week we discussed the proof (due to Daubechies, Landau, and Landau 1995) of Rieffel's incompleteness theorem using elementary von Neumann algebra theory but avoiding Rieffel's intractable coupling constant argument. This week we discuss the proof, (from the same paper and based on time-frequency analysis ideas) of the existence of the coupling constant for the von Neumann algebra generated by the basic time-frequency operators. The significance of the coupling constant will be mentioned.
