Abstract:
A complete description of multipliers of Fourier–Haar series in Lorentz spaces is given. Necessary and sufficient conditions for sequences of complex numbers to belong to the class m(Lp,r→Lq,s) of multipliers of Fourier–Haar series are obtained.
Keywords:
Fourier series, Haar system, multipliers of Fourier series, net spaces, Lorentz space.
