| Popis: | Let W =(Wij ) be a fixed m × n weight matrix, and let the W-weighied l1 , norm on Cm×n be defined by Given weight matrices U,V,W, of orders m × r r × n and m × n, respectively, we begin by proving that a constant μ > 0 satisfies In the second part of this note we restrict attention to a single weighted l1 norm on C n×n ,and show that We conclude that may be quadrative without being multiplicative on C n×n . |
