Some uniqueness results for functional damped semilinear differential equations in Fréchet spaces
The author provides uniqueness results of mild solutions for some classes of first and second order semilinear damped functional and neutral functional differential equations in Fréchet spaces. The proofs are based upon the semigroup theory and a nonlinear alternative of Leray-Schauder type for contraction maps in Fréchet spaces due to Frigon and Granas.
