In this paper, we investigate the problem of trigonometric multipliers in the sequence spaces λ_p,_q. Embedding theorems of the Lorentz and Besov spaces into the space of trigonometric Fourier series multipliers are formulated.

Lorentz and Besov spaces , M^{p1, q1}_{p0, q0} spaces , trigonometric Fourier coefficients
