Abstract
We study the question of the number of linearly independent solutions of the equationy (n) (x)+(Fy) (x)+ρn y (x)=0,x∃ [0, 1], in which F is a bounded linear operator acting on various normed function spaces. A number of assertions about the asymptotic behavior of these solutions with respect to ρεℂ, tending to infinity are established.
