Perturbation of Linear M- Accretive Operators in a Hilbert Space |
| |
| Abstract: | A sufficient condition is given for the sum A+B of a linear m-accretive operator A and a linear accretive operator B in a Hilbert space to be maccretive. This condition seems weaker than those given before. Thus some theorems on the perturbation of linear m - accretive operators are covered by Thearem I . Two applications of Theorem I are also given. |
