Abstract: The nonlocal unique solvability of the abstract Cauchy problem for an equation in a Hilbert space with locally Lipschitz nonlinearity is proved. Applications of the main result to the analysis of direct and inverse problems for the Landau-Khalatnikov equation are considered.

Key words: Cauchy problem for a differential equation in Hilbert space, existence and uniqueness of a solution, direct and inverse problems for the Landau-Khalatnikov equation.
