Abstract
Let A be a closed linear operator in a Banach space, and let n ≥ 1 be an integer. If the resolvent λI − A)-1 is an entire function of λ∈ℂ of order < 1/n or of order 1/n and minimal type, then the equation dn u(t)/dt n=Au(t) has only the trivial solution u(t)≡0. An example for partial differential equations is given. Generalizations are indicated.
