Abstract: Using one-sided Steklov means, we introduce a new modulus of smoothness in weighted Lorentz spaces. The direct and inverse approximation theorem for this modulus of smoothness are proved. Also, we estimate the rate of approximation by the Borel and Euler means in weighted Lorentz spaces.
Keywords: weighted Lorentz spaces, direct and inverse approximation theorems, Borel means, Euler means.
