| Research Abstract |
We introduce two notions of semigroups of Lipschitz operators associated with semilinear and quasilinear equations respectively and establish approximation theorems for such semigroups. The feature is to propose a new type of stability condition which admits “error term”. We also discuss the solvability of semilinear equations with the help of comparison theorems for Volterra equations.
