Correction to "on functional duality in multiuser source and channel coding problems having one-sidedcollaboration"
In the above titled paper (ibid., vol. 52, no. 7, pp. 2986-3002, Jul. 06), there is an error on line 8 in the first paragraph on the left column on page 2992 regarding broadcast channels. The equation is not correct and thus the argument given in the rest of the paragraph is not valid. A correct argument is presented here.
