Abstract |
|
The classical logarithmic convexity inequality, for solutions of u′ = −Au with A a self adjoint operator on Hilbert space, yield that u is small at intermediate times, 0 < t ≦ T, provided that u is small at T and bounded at 0. Use of the Carleman inequality for analytic functions allows one to easily generalize this result to the case of operators A which are generators of holomorphic semigroups on Ranach space. |
