# Inequality of the Turan type for trigonometric polynomials and conjugate trigonometric polynomials in $L_0$

We study inequalities of the Turan type for trigonometric polynomials and conjugate trigonometric polynomials in the quasinorm of $L_0$ and derivatives of any order. We present expressions for constants in these inequalities and obtain double-sided estimates for them.
