Row and Column Spaces of Matrices over Residuated Lattices 1
... Throughout the paper, L denotes an arbitrary (complete) residuated lattice. Common examples of complete residuated lattices include those defined on the real unit interval, i.e. L = [0, 1], or on a finite chain in a unit interval, e.g. L = {0, n1 , . . . , n−1 n , 1}. For instance, for L = [0, 1], w ...
