The author studies necessary conditions for nonselfadjoint ordinary differential operators to have basis systems of eigen- and associated functions in some spaces, and be uniformly minimal. Theorems are formulated and proved for various such operators with anti-a-priori estimates. Results are useful in advancing the theoretical research of ordinary differential operators.
