A note on product-sum of \(L\)-\(R\) fuzzy numbers. (English) Zbl 0844.04005

Summary: E. Triesch [ibid. 53, 189-192 (1993)] provided a partial answer to R. Fullér’s [ibid. 41, 83-87 (1991; Zbl 0725.04002)] question about the membership function of the finite sum (defined via the sup-product-norm convolution) of \(L\)-\(R\) fuzzy numbers. In this short note, we prove the other half.
