Lower bounds for solutions to a class of nonlinear integrodifferential equations in hilbert space
Frederick Bloom, Jack K. Hale, J. Hopkinson · Applicable Analysis · 1980
Growth estimates are obtained for solutions of the abstract nonlinear initial-value problem where H + is a Hilbert subspace of some real Hilbert space H, with topologically as well as algebraically, and with H _ being the dual of H + via the inner product of H and denoting the space of all bounded symmetric linear operators from H + into H _.
