Convergence of Difference Approximations and Nonlinear Semigroups
Shigeo Kanda · Proceedings of the American Mathematical Society · 1990
We give a convergence theorem for the difference approximation for the evolution equation $(d/dt)u(t) \in Au(t)$ and a generation theorem of nonlinear semigroups for "directed" dissipative operators $A$ in a real Hilbert space.
