| Popis: | In this note we prove some results on the m-accretivity of sums and products of linear operators. In particular we obtain the following theorem: LetA, B be two m-accretive operators on a reflexive Banach space. IfA is invertible and (A′)−1 B′ is accretive thenBA −1 andA+B are m-accretive. |
