Abstract
We show that, whenever the linear operator A is symmetric and densely defined, on a Hilbert space, then the abstract Cauchy problem d/dz u(z ) = A(u(z)) (z is an element of C), u(0) = x has an entire solution, for all initial data x in the image of e(-<(A)over bar A>), which is a dense set.
