Abstract :In this paper we discuss and investigate trigonometric approximation in weighted grand variable exponent Lebesgue spaces. We also prove the direct and inverse theorems in these spaces.
Keywords : weighted grand variable exponent Lebesgue, Sobolev and Lipschitz space, maximal operator, modulus of smoothness, best approximation, Jackson and inverse theorems, K functional
