Unstable manifolds of a class of delayed partial differential equations with nondense domain
Chiraz Jendoubi · Annales Polonici Mathematici · 2016
We present an unstable manifold theory for the abstract delayed semilinear Cauchy problem with nondense domain $$ \frac {du}{dt}=(A+B(t))u(t)+f(t,u_t),\hskip 1em t\in \mathbb {R}, $$ where $(A,D(A))$ satisfies the Hille–Yosida condition, $(B(t))_{t\in
