Well-posedness for time-fractional evolution equations by the Yosida approximation

S. E. Chorfi, F. Gölgeleyen, M. Yamamoto

We consider an initial value problem for a time-fractional evolution equation in a Hilbert space : $$ \partial_t^α (u(t)-a) = Au(t) \qquad \mbox{for $0<t<T$}, $$ where $\partial…
