N2 - We consider an equation -y″(x)+q(x)y(x)=f(x), x∈R; (1) where f(x)∈Lp(R), p∈[1,∞] (L∞(R):=C(R)), 1≤q(x)∈Lloc1(R). We study requirements for a weight function r(x)∈Llocp(R) and for q(x) under which, for a given p∈[1,∞], regardless of f(x)∈Lp(R), the solution y(x)∈Lp(R) of Eq. (1) satisfies the inequalities: r(x)y(x)p≤cf(x)p, y″(x)p+q(x)y(x)p≤c f(x)p, c=const.
