Abstract
In this paper, we give some sufficient conditions for which the differential operatorP(λ=P 0+λP 1+...+λm−1 P m−1+λm, depending polynomially on the complex parameter λ, verifies the following statement: there exists λ0 ∈ ℂ,u o=0,u 0 ∈ ℒ(ℝn) a Schwartz space of rapidly decreasing functions, such thatP(λ0)u 0=0-.
